Sortable maintained window
 

I'm sure this has been asked before, but I can't seem to find any info on it. Is it possible to sort the maintained spell window? What I mean is to separate by who cast it or by timer, separate food/drink, stuff like that. Can it be done? I'm guessing not, but figured i'd ask.

No, sorry. We have no control over the order of icons in the maintained spells window... but you do! They show up in the order that you cast them, so in a way, you can reorder them.

If you're asking about the spell effects window, which shows all spell effects on your character, including effects from your group, revive sickness, food, drink, equipment effects, etc. no, those cannot be reordered.
