Reactions like Solasta isn't possible with Larian unless they re-designed an entire platform meant for DnD 5e and not their previous games, which would set development back years. They are going to move forward with what they have and make it work.
The masses will love it, the fanatics that are on the forum and/or Reddit will not. It's just time to face reality and stop wishing for things that aren't going to happen.
Im not quite sure about Larian's possibilites, or limitations ...
But i would dare to presume that adding certain ("spells" for example) icons, dragable anywhere on hotbar , that would open all (spells in that example) related things at once in popup menu.
That seem perfectly doable even without scraping any so-far development. :-/
