I'm getting the impression radioactive_lego is using either the Press (?) or Mixed option for activating hotbars, not the Hold option. So hotbars stay up after simply pressing R2/L2, until R2/L2 is pressed again to close the hotbar, rather than staying up only while R2/L2 is held in and disappearing when they're let go.

This option would be miles and miles more useful with that setting, I think. At least for me, using the Hold option, it doesn't break the flow that much to let go of the trigger, hit a button or two, then hold in the trigger again.

But if you're keeping the hotbars up on a single trigger press with the other setting, it must be maddening to have to turn them off, target/confirm/whatever, then turn them back on, etc.

Really, though, either way, I don't see the harm in adding this as an option.
