 ## Now:
 - outfitter
-
-## Small jobs
 - Clean up scripting & errors
 - Clean up sprite content (and content in general)
+- Arbitrary scene names
+- Text style, color, formatting
+- Flying UI
+- Mouse colliders
+- Clean renderscene/UI scene/change scene on land
+- UI captures input?
+- Scriptable renderscene: script decides which parts to show
+
+
+## Small jobs
 - Fix window resizing
 - Debug: show mouse position
 - 🌟 Better planet desc formatting
