Too Few Maintained Spell Icons
 

I am only able to see a maximum of 12 maintained spell icons and it is killing my tactics.

Any suggestions?

Thanks

Simple.
 

Just right click on the spell/hotkey bar and open a new one. I have 4 of them open.

nah
 

I should have been more clear.

The "Maintained Spells Window" is by default located on the left side and can be viewed by pressing Alt-M.
This is the one that seems limited to 12 icons.

For DoTs and HoTs it is crucial to know when they fade so that you can restart them and this is very hard to do without seeing the icons.

I know how to add more "Hotkey Windows" and have four myself.

easy. right click the window, click window settings, uncheck the "lock" setting, resize the window to something like 12x2, recheck the "lock" setting, click ok.

nope
 

The first thing I did was resize the window...nothing.

Resizing works ok for the Spell Effects window but the Maintained Spells window is still limited to 12 icons
