Yes, this is what was needed :)
v.1.9.2: Added format strings to advanced text formatting for visible (group) tabs and all tabs.
This allows tab counter to count both all tabs as well as tabs in the current visible group.
It remains only to localize all format strings.

Nice add-on, but this upset me: "Count will now only take into account visible tabs. Hidden tabs (such as tabs in other groups) are no longer counted".
Please, do the choice for users: 1. Show the count of tabs in the group; 2. Show the total count of tabs; 3. Show both, eg 7 / 19.
