I can not change the iconsize for statusbar plugins.
Only 18x18 icons are allowed.

Of course you can exchange the icons I used for this
app, with your own icons.
Just replace my icons
/usr/share/pixmaps/active-desktop-sp/
(names are
active_desktop_1.png
...
active_desktop_9.png
with your.

Feel free to post your icons here. I would like
to see those.
