Here's something I've wondered for a while, are you planning on stealing quality of life ideas from Toybox? Like highlighting the scrolls a wizard can learn, shift+click to move entire stacks instantly, respec companions from scratch, refilling belt items after use automatically...
These and others like it are SO good and I feel bad for people who can't mod their game.
EDIT : The highlight is already in apparently, nice!
Respec companions from scratch won't happen in unmodded game, they had lives before you and their skills reflect it. That's one of those minor but important things that gives them personality, instead of making them plastic dolls. Refilling belt items or autobuffing is also unlikely, as it automatizes the gameplay too much, and in our opinion that'd kill some of the classic RPG magic the game has, slowly turning it into a conveyor. If you wish to do it anyway, you can always use mods, that's the reason why we give the tools to make them in the first place :)
Some less dramatic QoL things like inventory search and moving stacks are on a "would be nice to do" list, so it's mostly about time/budget constraints and will most likely make it into the game in one form or another at some point.
