Ben's Quarters adventures in application development ...

In today's tabbed browsing world, maybe you find yourself opening and closing tabs left and right.  If you're into the keyboard shortcuts, that would be Ctrl-T and Ctrl-W respectively   What if you accidentally close a tab?  This happens to me most often when either I thought I was done with the website I was on, or I thought the tab I was on was a new tab with nothing to go 'back' to.

Fortunately, the good browsers out there offer a Ctrl-Shift-T keyboard command to open up the last tab you closed.  I like to think of it as the "ctrl-z of browsers".  This keyboard command is very handy because you can actually keep pressing Ctrl-Shift-T to open up all the tabs you previously closed.  Each tab you re-open not only opens up with the page you were on when the tab was closed, but the browser history for that tab is also preserved.  So once you re-open a closed tab, the entire 'Back' button browser history is there.

Ctrl-Shift-T works in Firefox and Chrome.  It doesn't appear to work in Safari/Windows and doesn't work in IE7.  That's what I meant by this keyboard shortcut working in 'good' browsers   It does appear to work in IE8.

Since discovering this keyboard command it's something I use probably at least once a day.  Sometimes many times a day!

I spent a couple of days using Chrome as my primary browser.  Chrome came out of beta on December 11th, and its version number is already over 1.0.  There's a number of nice things I like about Chrome, but for now, I've switched back to Firefox.

There's two big things I like about Chrome.  I like how each tab runs as in its own isolated process within Windows.  I leave my browser open all day, usually with Gmail open in one tab at a minimum.  Not all the memory from closed tabs in Firefox seems to get reclaimed and firefox.exe usually shows up using around 150 KB of memory mid-day even if only Gmail is open at that time.  Firefox 3 is supposed to be a lot better than Firefox 2 for preventing memory leaks, and I'm sure it is.  150 KB of memory is not a big deal, either.  But the Chrome architecture of running each tab as its own process has the big advantage of basically guaranteeing all memory used for a tab will be completely reclaimed once that tab is closed.

The other big item I like about Chrome is how you can easily drag a tab out of the Chrome window into a new Chrome window.  Especially if you have multiple monitors, this is a really great feature when you want to see two or more tabs at the same time.  I was breaking the tabs out into separate windows when composing an email in a web interface or when typing messages on forums / blogs.  I could compose my messages while seeing other information I'm referencing in the other Chrome window at the same time very easily.  After I was done composing, I would drag the tab back into the main Chrome window.

I'm back to Firefox now as a primary browser because of some features not yet available in Chrome.  The big one being Firebug.  I didn't realize how often I right-click on an element to inspect it in Firebug, check the Net tab, etc.  I also like how when you change the text size in Firefox (i.e. zooming text), how Firefox remembers the size you last had when coming back to a website.  In Chrome, you have to adjust the text size again every time you go back to a website.  Also, URLs in the status bar when you hover your mouse over a link are often truncated because the space Chrome allocates to show the URL in the statusbar seems to be a fixed width.  There's actually a lot of extra room to show the entire URL, and I hope this gets resolved soon.

So for now, Chrome is not yet ready for prime time (for me).  Google is of course working on lots of improvements for Chrome.  This includes adding an extensions framework so people can start developing extensions for Chrome.  I haven't heard of any type of Firebug for Chrome initiative, but for me, something like this would add mega value to Chrome.  I plan on sticking with Firefox which has treated me well, but checking back on Chrome every once in a while.

I still see web-based and desktop-based email applications which only support folders to file email away into.  I'm a Gmail user and have the luxury of using tags to organize emails.  Tags are actually known as labels in Gmail.  But whatever the name, tags are in my mind, unquestionably superior to folders.

I don't remember talking to anyone who said they do not find the tag system better than the folder system.  And even if a person felt more comfortable associating an email with only one identifier, a single tag can be put on an email as multiple tags are of course not mandatory.  Given the benefits of tags over folders, I can't see why any company developing an email application would not want to replace the old, inflexible folder system with a tagging system.

Folders and tags are not limited to just the email world.  They exist for bookmarking urls too.  Tags were introduced in Firefox 3 which now supports both folders and tags.  I don't regularly use other browsers, but taking a glance through IE7, Safari and Chrome, it appears FF3 is the only browser among these that supports tagging bookmarks.  FF3, Safari and Chrome also have search capability to find bookmarks.  This may seem like a given, but I don't see any bookmark searching capability in IE7.  FF3 also introduced a very cool concept of saving the criteria used in a bookmark search as a "virtual bookmark folder" so you can later click on the virtual bookmark folder to see real-time bookmark matches satisfying the saved criteria.

I use multiple tags for my bookmarks too.  I've actually been using Google Bookmarks since before FF3 was released, so I've unfortunately never spent any significant time using FF3's bookmark tagging.  The big advantage of Google Bookmarks being that I can access all of my bookmarks on any computer since my bookmarks are stored on Google's servers.  I just need to log into my Google account to access these bookmarks.  Google makes it easy to bookmark a page too with a bookmarklet they provide and I keep in my Firefox bookmarks menu.  So bookmarking a site into Google Bookmarks requires just as little work as it would be to bookmark a site into Firefox.

Whether it be emails or bookmarks, tagging has proved to be really helpful when looking for stuff later.  There's probably lots of areas other than email and bookmarks where tagging would be useful as well.  If you're stuck with the restricting folder system for emails or bookmarks, I'd suggest requesting your provider to upgrade their app to a tagging system or, if possible, move to a provider that supports tagging.
