Wow, that version is very nice
I use the theme GrApple (Default Pro) - and it has been updated for the new prefs.
Just one glitch (with the default theme as well), when I open a new window or tab, the disabled reload arrow show as a part of the home icon plus a piece of another icon.
Active reload button is fine.
It behaves that way with small icons only in the toolbar, big ones are fine.
Regarding the toolbar, when editing it all the possible buttons are not available (reload, backn forward, stop, and so on …) , I don't think it's normal.
Last stuff, regarding the new prefs, any clue if it's possible to remove their resize/fade in effect, which takes a lot of CPU for doing nothing ?
