Haven't really overhauled my last design over the past few months but I think I've ironed a few of old wrinkles out. Honestly, I'm still not thrilled with the kgPanel borders but I haven't found many alternatives I like or had any great inspirational moments.
For those interested, the zone text down at the bottom is a placeholder for my level 80 characters - it's a TourGuide feed on my alts. The empty space in the combat screenshot above my player unitframe is for my pet. I normally keep the Skada windows hidden, but I can pop 'em out with the databroker button. Finally, I usually have clock+coords hidden on my map but I enable them from time to time if the need arises. Sorry about the lame party screenshot.
I like that ;) good job. If you want to lower the combat log tab / text so it's inline with the other tabs, add this <snip>. I just added it to fane. I'd remove the eaves drop "Player" "Target" texts, they don't stick out like a sore thumb or anything, just don't look right imo :p And I'd also change the colour of your targets dot/magic timers, very vibrant. Just my opinion ofcourse :) Like your work!
I appreciate the tip on the Fane tab setting. Honestly, I never even noticed it being slightly out of line but now that you've mentioned it... hehe. I like the EavesDrop texts, so I probably won't remove those. I've also meant to change the ClassTimer color defaults for a long time and I just never seem to get around to doing it.
I'm probably going to stick with this as we come up on the WotLK release. I'm not overly fond of the borders, but there's not a ton of options I've found and I haven't felt creative enough to make my own with panels. (Read: Lazy.)
I'll second Phanx's stance on the Curseforge profile page. It lost a lot of utility it used to have. Not sure the new feature set for the wowace page is a better alternative to what is, arguably, even more of a developer focused site.
