We should have the option to disable the ability to scroll to a grenade. I’ve accidentally thrown grenades twice because I scrolled to my “other weapon” while clicking.
Pressing Q to swap instead of scrolling helps, but is not useful while you have the infection scanner. Using the numbers to swap can also prevent this, but I can make the same argument in favor of my case.
Of course the option to scroll to the grenade should still exist, but we should be able to turn it off.
