 ## Misc Improvements
+- Surround DFHack-specific UI elements with square brackets instead of red-yellow blocks for better readability
 - `hotkeys`: don't display DFHack logo in legends mode since it covers up important interface elements. the Ctrl-Shift-C hotkey to bring up the menu and the mouseover hotspot still function, though.
