@burnout426 You can't add tags. They are added automatically, but now I'm thinking that it's intentional because at first the tags did appear and the app icon splash screen etc. were added. In fact, I have another mod that also has these options and they aren't shown either. The only mods that have these tags are the official Opera GX ones, which leads me to think that Opera itself does it on purpose... XD (Also, I didn't modify the mod code to add these new options, but one day they didn't appear.)
