Ok I wanted to give you an update on how this is all turning out.
First off you will need to know that to do exactly what you wanted so far just hasn't proven doable due to bugs and limitations. With that in mind however I set about visually reproducing what you wanted even if it isn't all exactly combinerd in one window. With snap-to-grid arrangement you can pretty much duplicate what you wanted, but the info is in a few seperate windows. I hope that in the end that will be good enough for you.
Now i've tried to go as much as possible to your mockup and guidelines though there were a few areas that I wasn't sure on and a few areas that might work better in other ways. Don't be afraid to ask for tweaks or changes here and there once I get this out to you. I don't mind.
Right now the way I have it all is working perfectly, but I have NOT yet resized any of it. For two reasons. First reason is I have been focused on functionality first and once thats good I will work on resizing. The second reason was I wanted to be absolutely sure you wanted it shrunk and HOW you wanted it shrunk (horizontally, verticaly, both) because even the default sizes (all based on the raid window) seem awfully small to me.
I'm going to attach two screenshots here then the XML files. Basically the way it works is you do have seperate target, impled, player, group, and raid windows but they are all designed to work together to create the unifed look you wanted. Also of note, and this is an area I can change that I wasn't certain how you wanted it, I current have the player info in the player window, but I also added the player name/level/bars into the first slot of the group window. The main reason I did that was because the raid window would normally show you as well, and so by adding you to the group window it all lined up better. Again that can be changed tweaked.
All the windows are szied on 5 pixel boundries so they snap together seamlessly. To solve the double edge problem of bugged gropu dynamic data that prevented me from pulling it out of the group window and the issue that you aren't always in raid group 1, I left the gropu info in the gropu window but made the raid/gropu windows in such a way that you can perfectly slip the gropu window into whatever spot is needed in the raid window. To do this you will find each group section in the raid window has a small button in the upper left corner (only shows up on mouse over of that specific section). Click that button will toggle that raid gropus visibility. So if for instance your group is in raid group 3, you would simply hide raid grroup 3 then slide the gropu window in its place. It will look visualyl like it belongs there
Just line up the modded implied/target/player windows as desired and the look should be pretty darn close to what you wanted.
I apologize that the screenshots here only show a 4 person raid (2 per 2 groups) but at this time of day on test its hard to get some people together
And we're all in different zones so some bars are greyed out.
The first screenshot here shows the looks. It also shows the gropu window to the right of the raid window so you can see how they are essentially the same. The second screenshot I hide group 1 from the raid and slid the group window into its place. Visually it looks like it belongs there
