Advanced multi-select tool for non-gradient fills
Fills that don't have gradients (e.g. the standard fill) cause area multi-selections to be immediately lost. This is highly frustrating if I've just spent a lot of time selecting many tiny areas.
It's also a problem if I have a brush selected and several areas selected, I don't know if it's safe to even touch the Fill tool menu, because if the last-used fill was not a gradient fill, I will immediately lose my area selections.
I'd like to see either solid fills support multi-selections, or at least show a warning if the chosen fill doesn't support multi-selections.
Immediately cancelling a lot of selected areas is a poor user experience and adds stress where it shouldn't exist.
This problem is extremely frustrating!
