Nobody else is hoping for improvements to the control scheme for the party ? It sounds as if the collective hope is dying ...

Well, with the risk of sounding like a broken record, I'm hoping for
- Improvement to the control scheme (Selections instead of just Groups, Ctrl+Click on portrait to add/remove from selection, party formation/marching order, ...).
- Improvement to the hotbar, improvement to the spellbook and similar menus.
- Improvement to the "looting - inventory management - selling" cycle.
- Ability to use the party as party, outside of just having more HP and actions during combats. Notably, being a party during cutscenes.

Generally speaking, I'm hoping for improvements to the game's general usability and playability.

I would also welcome attempts by Larian to care about immersion (removing the biggest "hey, I'm an in-world character but let me tell you about this video game functionality or limitation" moments could be a place to start).

I'm also hoping they have spent as little time as possible introducing new game systems (e.g. instruments) that the patch will focus on improving what already exists.
