Layouts was the hardest thing for me to figure out how to work it. But once the light goes on - of course!
In Layout, make multiple layouts... I see you have one called "Raid" make one called "Raid2" and "Raid3"
Lets say on your player frame, you want to remove all the buffs and debuffs (because you use something like EBB). Open up Raid2, edit the layout to turn off all buffs and debuffs.
Then in your units "Player" on the layout dropdown, select the layout "Raid2"
Now anytime you make a change to layout "Raid2" it affect your player frame.
You probably want to see your target's buffs and debuffs (if your dps), so in layout "Raid3" you would leave them on. If you went back to your Unites and "Target" on the layout dropdown, select "Raid3".
Any future changes to a layout would affect all groups and or units that the layout was assigned to.
I am really novice at this, but I did figure out and I know I like step by step explenations. Now to see if I can figureout the Text contents....that looks like coding though
