Feature Request: Negative Filtering
As someone with a considerable game collection, 1500+ and counting, I would like to see a simple feature added to filters.

Right now, if you open up filtering, you're able to click categories or add store categories to narrow down what you're looking for. I would like to ask for the option to add a "-" operator in front of store categories, or right click a category, to specifically *remove* that tag from the list of games.

For example, I can omit any game that has a co-op or multi-player feature by right clicking their check box, or I can type -roguelike or -cozy to omit any games that have earned that particular store tag.


Otherwise, the workaround I've had to adhere to is creating a temporary category of every game *with* the tag I want to avoid, creating the desired filter, creating a category for that search, and subtracting the other category from the second category. It's incredibly tedious.

Honorable mention, an "Or" operator would be welcome as well, letting you create a dynamic category for say Metroidvanias *and* Soulslikes
