 ## [Unreleased]
 ### added
+- score number: bounding area
 - configurable key bindings for many editor actions
 - QWERTY+ASDFGH keybindings for the tile tools
 - OS clipboard copy/paste, with fallback to old behavior when copying
+- cut selection
 - in-grid text comments (not yet editable in-game)
 - changelog file
 - (dev) sub-tick visualisation in debug mode

 - blueprint rotation?
 - settable marble start direction?
