I don't know if I already suggested it (I think I already did), but would be great if QMC2 filter to show only specific system groups from category.ini.
For example, I only want to see "Home computers" in the list. Then I select in "Home Computer" in a check box.
I know that QMC2 already have the "View games by category", but I'm suggesting a different aproach, which just allow system to be show by a criteria (Ex. I want to see only every Home console already emulated in release order). That's not possible with current builds.
Thank you!
