Feature request: Button for deselect all mods and make selected mods more visible in modlist edit mode

[CommandDDOS]

sometimes it takes too long to deselect all unwanted mods. It would be nice to be able to deselect all selections with one click in the category being browsed

it is easy to scroll too fast and "miss" selected mods due to the rather small size of the button itself. Changing the colour of the mod name or colouring the background next to the mod name to something would be more eye-catching
