So we end up with " , in category foo" if subtextLabel is empty?

Not needed?

I don't understand this focus stuff at all but if it works..

Can we perhaps bind the "isCurrentItem" to activeFocus instead of doing this in addition to incrementing/decrementing the index?

pretty much, i can make 2 different strings at all, the oddity if if it's a null string, i18n thinks it's a single patameter and complains about wrong parameters number

will give a try

what i'm trying to do here is to focus the next item when cycling items with tabs arrives to the last item, so yeah, it's a bit hacky but works

This ends up in a different .pot file to the translation domain of krunner which is using this lib, I think you need to i18nd
