It is very nice (especially, because of showing new mail icon properly!), but there is something to improve.
1. It would be very convenient, if icon options contained an options "Click to move to current desktop and activate" and "Click to activate and change desktop". The matter is that by default a click hides a window, when it is open, or restores it, if it is hidden. Thus, if you want to have the window before your eyes, you need one or two clicks depending on the situation, or scroll the wheel twice (down and then up). It would be much more convenient to click once independently of the initial state of the window to make the window appear before your eyes (depending of personal taste: either by moving the window to the current desktop or by changing the desktop to the window).
2. The default icons are not scaled automatically in the system tray (KDE4). With some icon themes (crystalsvg) they turn out to be too small. I replaced them with custom icons (from /usr/lib??/thunderbird or /usr/lib??/firerfox directories), but in the case of firefox it initially scales too large, and I need to force it to disappear and reappear to make it be properly scaled. Probably, some interaction with system tray is broken.
Hi, as for 1. I think this is partially covered by the middle click.
