Even though AndreasV may be working on a systray docklet, I too would want one. Currently using DX for the tray, but it doesn't function correctly for some odd reasons. As with kkmenu, I don't like the way it works. It maybe updated, but I still don't like the idea of adding a small (shareware) software to another small (freeware) software. In otherwords, freewares should enhance shareware, not the other way around.
Anyways, a suggestion: Until OD can run with more than one instances, the docklet should work somewhat like the "Dock Taskbar". Instead of having small icons fit into one big icon, have the small icons as big as the "big icons", and the ability to replace those icons images. (hmmm, maybe this should be a suggestion for OD's new feature instead).

Doubt I'm making sense either.
