Not bad so far.. some things look a little different than 5..
One thing I don't like is the X to close the current window is now above the banner area where I could've sworn it was below it last time.
Whenever this comes out I'll actually register it though. Anyone know if keys work for both linux AND windows?
I can't tell any major differences yet between 5 and 6, but it still works great and that's all that really matters anyway.
Edit: Here seems to be an interesting new feature.. there's preferences as always, but now there's "Quick Preferences" if you go to file or hit F12. An interesting one: Accept Pop-up windows, refuse pop-up windows, or open pop up windows in the background. Hmm, I'll have to try some of this out.
