QOL Suggestion for 3.29 - Seamless switching between controller and mouse/keyboard

Whilst there have been minor improvements to controller support recently we still have the issue where if we want to switch control method it has to be done in options, breaking the flow/immersion of the game. It would be fantastic to finally implement seamless control so we can play the game with controller but manipulate stash or anything else via mouse and keyboard.

Many other ARPGs do this, and it would be a huge QOL change for those of us who enjoy the 'feel' of controller gameplay. Could this please be something that can be looked into for 3.29?
