I play on Stadia and there are 2 things you do all the time in BG3 which are excruciating to do on a controller.

To put all my characters into hide or unhide all my characters it takes over 20+ button presses. This is a lot for something you do all the time. The character screen currently has many buttons which are not used when on that screen. Can you please add something like (hold Y) to hide/unhide party? It would take me 3 button presses instead of 20+ to do something I constantly do. 1 press to go into character screen, 1 press and hold to hide, 1 press to exit character screen.

The ungrouping with pushing on the right stick seems to work ok, however, when I try and group my entire party again it can take me up to 5 full minutes to get this to work on Stadia. There should be an easier way to ungroup/regroup the entire party in 1 press. Splitting up into specific groupings can still be done with the thumbstick, but you group/ungroup your party all the time and having to spend 5 minutes to do this is almost enough to make me not want to play the game. It is really that bad on Stadia. Much like my suggestion to hide/unhide the whole party can you add (hold X) button press to the character screen which will group/ungroup the entire party? This will take a 5 minute struggle down to 5 seconds. Please add this for the controller players!
