Thanks.
The right buffs are target buffs, which has a limited use in Healing PvE but is more useful for other things (PvP etc). I have myself targeted in that screenshot.
The minimap is hidden. I don't find it that useful in a 3rd person game, especially when you spend a lot of the game zoomed out. When it is showing it's pretty close above the target frame, cos i figure if you're lost, you're lost :-)
One of the general concepts of the UI is to have a lot of elements able to be switched on and off with the buttons on the left and right of the main action bar. Currently the plan is to have buttons to toggle: the minimap, skada, all chat frames (I'm antisocial sometimes, I admit it), a huge trade channel panel (very useful on high population servers), and enlarged pet frame, and Raid Frame profile switching, and also toggling a panel with all the action bars with keybinds on them (which you have hidden when playing).
No screenshots yet, the raid frames are what I'm working on at the moment. I'm using Grid because I like it. The screenshot posted is healer mode and with frames that size the space below will accomodate up to 25man (I think). for 40man they will be vertically smaller but I'm fine with that because there isn't really any serious 40man content. When DPS/Tanking the raid frames go over to be a column on the right of the screen and the space on the middle is for more elaborate DPS bars and timers and stuff.
