I've been trying to learn to like the admin UI in 2.7.x since 2.7.1 came out.
It's not happening. WHY do I have to burn so many CPU cycles just to write a post? Why do I need all that jquery whizbang ajax? Just because you CAN do something, doesn't mean you SHOULD. I'm glad the dev team knows AJAX, and I'm sure they've done lots of work for lots of clients they're very proud of. Now may I please have a responsive, easy to use UI that takes less then 1:10 to get to a UI to write a proper post?
Yes, I have gears installed. This laptop is 2Ghz/32bit with 2G RAM. I can compile a kernel in 25 minutes; it's NOT my hardware. When I try to use the admin site on win32, there's so many UI bugs (overlapping fields, mostly - on 2250px wide 16:9 LCD) that it's just as unusable.
I would rather see the dev team energy going towards developing a solid admin API, with attendant reference implemention, that would make it possible for us non-UI-coding types to develop our own admin areas, with the features that we really need easier to get to than the features that WP thinks we might need.
