   - editing
   - add to all intro levels
-- highlight regions with background colours
 - UI layout engine
   - global scale setting
-- button + binding to flip selection that is being pasted

-    - speed up/down
-    - grid cursor movement and placement
-    - grid zoom and pan
 - more levels
 - scroll output bytes
 - timestamps in solutions and blueprints
+- lock tile types for early levels to make it less overwhelming
 - display tool variant more clearly (it's not obvious there are more states)
 - better text rendering
   - font selection (probably a lot of work)

 ### undecided
-- hide some tile tools in early levels to make it less overwhelming
 - footprint score (tiles that were non-empty at any point in the run)
 - option to use 8-bit marbles?
 - blueprint rotation?
