This is a dream: I would love to see a custom UI layer, it doesn't even need to replace the UI layer of the default ui. It would sit under that, but still track with the user POV or user camera. That would allow me to build a boarder around the screen for a GM this would let me bed in npc character sheets token actions, Attributes. And for the players, they would get a thematic screen border with similar features for their own character. I imagine it like an RTS or MMO ui overlay, or in this case underlay. As I imagine it sitting under the default UI of roll20. edit: Just to rain on my own dream: Of course it might be impossible to scale correctly to the vast variety of screen sizes, so perhaps a GM only feature as I would build the ui to fit my screen. edit: I just remembered, it could be implemented similarly to how token actions and the macro bar currently appear. They could be on the same layer or the ui layer could be under the macro bar and token actions bar. But thats where I'd put it. And those bars already have rudimentary screen scaling by wrapping the buttons around to a newline on narrow screens. Its a dream for sure.
