This was quite proper made still it lacks alot of documentation (The read me only says how to import).
I tried atleast 1000 times to click those damn icons and you know what, it didnt work. Just dragging box could pick them.
The information about the spell is a little bit hidden for my taste, to small scaled to, would it be better to keep like a black box (or a multiboard) next to the icons and display the info there as it now really needs to change colour.
Else I like it but dunno if it's true that you mention about it is MUI, you maybe can do this but I cant display all at ones for multiple units
