Example of Addon:
As I was reconfiguring my UI today, and as usual Parenting my eePanels - while doing that a thought came up into my mind. Wouldn't it be possible to make a mod that create some kind of invisible boxes, which you should be able to control. Basicly invisible boxes that moves from (x1,y1) to (x2, y2) on Event. Fx. You're entering combat, the invisible box moves from (x1,y1) to (x2, y2) and it takes X amount of seconds. So you should able to use these invisible boxes as parents for your eePanels.
I really lack this option of having moving frames on Events, Why?
Simply because you don't focus on the same thing at all times. As discussed in the huge thread on Elitist Jerks forums about designing UI - the overall concluction is that important information should be centered in/of your screen. When you're standing AFK in Shatt completely ungrouped and bored - what I mainly focus on in such a situation is the chat, so I want that centered and "in focus". While I'm raiding tho, as a healer I want my Raid frames to be "in focus" though I still want the chat, but not as highest priority - so if I was able to push the chat to the side and put the raidframes in focus, that would increase my effectivity.
As I'm not able to code LUA myself (only done simple HTML and a bit of ActionScript in Flash), I would like to share this idea - in hope for developer will take this idea up and hopefully solve this problem by an addon. Make sure you don't misunderstand this, I'm not sitting as a kid on my lazy fatass and screaming "I want I want" as of course I'm not demanding this addon, I'm just trying to highlight this problem and hopefully some with the ability to solve the problem, will.
