Slider is more annoy users now, maybe it would be better if you made brightness control as it is on any other console? Menu+vol± as I remember? But wait, what to do with slider? I have an answer! It would be cool if user have a two option - made it works like button, that can be configure in retroarch - in up position button is released, in down position - pressed
Good for shortcut combo, or for toggles with “hold” option (like rewind, fast forward) or maybe there is button for some games that you can assign this slider to make it more engaging, idk
D-pad to stick mode toggle option can be useful too, I think
And another option - make it works like two buttons - send short pulses when toggle
Toggle up - button 1 pressed for 200ms for example; down - button 2 for 200ms
(Open and close menu, for example, with this combo would be cool!)
Would be so cool if you give option to user to decide what option he prefer
Slider mode : impulse and hold
Thanks!
