So yes, whenever I get a beta key, I'll be doing the following:
Playing the game a bit mod free. The goal being here to see how all of the new ui features are supposed to work. More specifically, I'll be playing a death knight a good bit to learn about how runes are displayed etc.
After that, I'll be updating my addons, one by one. Here's what to expect:
Bongos
Will be reaching end of life status. It will not be updated for Wrath.
Dominos
Will be updated to Dominos 2.0.x to signify Wrath compatibility. Beyond the obvious things like support for the Death Knight class, I expect to add in a one bag option (may be pre wrath depending on how long it takes for me to get a key), and to hopefully fix the "You need to bind your keys for stances to work" issue. Unless something absolutely drastic happens, your settings will not be reset.
Bagnon
Will be updated for Wrath compatibility. Main thing I plan on doing is a major code review (again).
Combuctor
Fate is up in the air at the moment. There's a good bit of UI issues I need to rectify before I can move further on the project.
OmniCC
Will be updated for Wrath compatibility. Thinking about adding a per character settings option, along with the return of the flash. The big issue I want to fix is to make the pulse option not kill FPS, but that might not be feasible.
Sage
Will be updated for wrath compatibility. Sage 3.0 will be a major revamp, at least on the backend. Shared Media 3.0 will be supported.
Sellfish
Will be updated. Nothing new will be added (its in support mode, obviously).
Ludwig
Will be updated. Will likely look at doing a code review, along with support for spells and trade skills.
