Totem timers...feasible for user contribution?
 

I see that totem timers are listed in the To-Do list.

These are more than a convenience really, because sometimes not being able to desummon a totem (without dropping another one) means pulling adds (my Shaman isn't 30 yet, so doesn't have the skill that desummons all totems, but even with that, seeing the duration timer of totems is also somewhat useful).

How difficult would this be for a user to work on and contribute, I wonder? Blizzard provides widgets for them, AFAIK, so would it just be a matter of putting them (back) somewhere in one of nUI's frames?

Well... the current version of nUI uses the default Blizzard totem bars, so the functionality should all be there. As for nUI6, I have created a high level shammy on the test realms and I will be using him to develop a more robust totem bar. In the meantime, nUI is compatible with all of the existing Totem mods, so you should be able to use one of them until I can incorporate their functionality into nUI6.
