Improvements to the Action Bar and Unit Frames ?

[Reaujien]

It just boggles me thinking of what SE's prioritys are...

It's understandable that some people may have anxiety over announcements from SE that they're making changes to something that seems to be very, very minor - in contrast, of course, to the overall major changes announced/expected. However, with any form of software - whether it be a video game or an enterprise-class application - there exist many features (visual or functional) that can be changed, tweaked, altered, etc., with relative ease compared to making changes to the underlying, or "core", functional/visual foundation of the game/application itself. Even so, if a game/application is undergoing major reconstruction, it's possible to add these sorts of changes/alterations as "quick fixes" without impacting the overall reconstruction project.

As a developer, I'm guessing that the changes they are making to the Action Bar and Unit Frames is something as simple as swapping out images or textures (or both) to the already existing visual system. I doubt they are making any alterations to the functionality of these features; I believe that was already done in an earlier patch.
