Sorry for the late reply! Your comment was marked as pending by itch.io, so I didn't see it until now.
Thanks for all the suggestions!
I'll probably rename the pack in the next update. Game store icons may come later, but for now I'm mainly making general-purpose icons instead of logos and brand icons.
I've already finished the next update, so some of the icons you suggested will probably be added in July instead. Also, changing "Gamepad" to "Controller" is a great idea!
I agree about having more categories too, the pack is already up to 12 categories. I'm planning to switch to CC0 in the next few days as well.
As for your paid suggestions, I'll definitely think about them.
Thanks again!
