It would be really cool if the systray would do the following things:

* ignore size the application requests for icons
* consider unscalable (non-svg) Icons as broken - scale as a workaround even if its ugly (its imho less ugly then the way things work currently). (bug report to the application in question)
* intelligently use the space provided if the panel is vertical (add support for setting up columns and rows in the tray)

all icons should have same size
