There was one big discusion about temporary skills ...
The best idea wich came out of it (in my honest opinion) was the idea that temporary icons, or recast icons should have replace the original spell icon ... aka, simply remove the spellslot cost for next use.
Problem here is that back in the old discusion, we had only spells like Hex, or Hunter's Mark, or Speak with Dead ... to recast ... so it was allways single icon.
Im not quite sure how to resolve this issue with (for example) Druids cantrip: Produce flame ...
Since casting that will give you another 2(or 3?) icons to use. :-/
Maybe put them all in one popup-window?

Also its certainly worth mentioning that you can adjust type of items wich will (or will not ofcourse) be automaticly added to your hotbar in setting (for example i have everything turned off, since i like to sort my hotbar myself).
