Allow smaller icon to avoid hiding on not so wide screens with many menus

[LouisCAD]

An option to allow the NyanTray to take only one or two spots (instead of ~4 at the moment) would be helpful to keep track of an IDE process while you're into another IDE or another project (because IDEs have lots of menus, which take precedence over NyanTray, which becomes hidden in this case as my tray is already crowded).

Regardless, thanks for this awesome plugin!
