I am not sure what his Command Fx is for seeing as we have a command visibility setting which will do the whole queue. His look a bit nicer but would be too large if you wanted to display more information. The Command Fx that
Anarchid refers to is the little colored circle that pings out of your cursor as feedback when you give a command. I think Floris wrote that too and it was included in custom formations.
I am not sure what the rezz halos are for. They seem like one of those small style mods that we don't need in the main game.
Self-D timer display is a decent idea. It could be a good idea to use our hovering icons framework to display it instead of using his widget. The framework is used for priority, armour state, xp and low power mode and deals with overlap. Including Wait would also be worthwhile.
