Thanks for offering help. Yes, I do know how to customize/edit themes, I just don’t want to do it with SP so that I can update themes to new versions without any concerns about my custom code being lost etc. Changing the wording on a button is just isn’t worth all the hassle (editing, testing, update issues, child themes, etc.) for me. It’s fine, I think my users will figure it out eventually.
I would change it to, e.g.
“Watched: 2 (1 new)”
Still takes little screen space, but is twice as informative (the first number is the number of watched topics, the second – the number of new posts in them). But it’s just a thought, not a feature request, because as I said, I’ll be fine even as it is, it’s not that big of an issue after all 🙂
