Interesting idea Landiin mate, I can see where your coming from with that...... Didnt work for me likes hehe ... They stay fine horizontal (as stated) but soon as you resize it to have say 2 rows or more it dont stick.. I even tried to stick in a VolumeFill property to the iconbank it didnt crash and didnt make any damn difference either lol
I can see this is going to be loads of fun if they add this nasty iconbank thingy to the Effects and Maintained windows

... Surely they wouldnt do that to me? would they?
