I just noticed the new interface.
I run Jitsi on Debian Wheezy 32-bit with xfce 4.10, default OpenJDK, nvidia video cards+nvidia driver.
-The input box reads: "r name or number"
-With xfce, the UI buttons that have text on them are not skinned (they look like standard java buttons - this includes the menu items too). Additionally, the fonts might differ from what is shown for example under Gnome. (This was always like this in Xfce, maybe now with all these changes you guys have a look at this - btw, Debian has Xfce as default for Wheezy...)
-The tray icon looks oversaturated (see attachment).
-The main window (contact list) header background color seems a bit too bright (see attachment).
But all in all it looks better than the previous one.
I like the new call window, maybe the record icon needs some work to make it more easy to guess what it means without having to hover the thick circle.
PS. The icons... Why is everyone wants to go back to black and white? Our displays can show millions of colors...
Seriously, while they look good from technical/aesthetical point of view (really, they do have a professional look, look better than the previous ones), i like better them if they are colored. Just a personal opinion.
