Opera Playground

Opera's debug tool, Opera Dragonfly, is very useful, if you actually use it, especially if you use it with Opera 10.0 beta or Snapshot. Unfortunately, I have heard some said Firebug is superior by far, or the like. But before imitating such lines and blogging so over again, use it by yourself to see if it is really so.

Along with the major update of Opera itself, Opera Dragonfly of Opera 10.0 beta got better than before.

If you like to use it often, it's quite troublesome to following the menu, Tool, Advanced and Developer Tool with your mouse. With recent Snapshots, you can open menu by hitting "Alt", then using keyboard, hit T, A and D in succession after that.
Even if you are mouse favorite user, for starting Opera Dragonfly, you will easily memorize "Alt > T > A > D", and like it.
