 ## Misc Improvements
 - `prioritize`: refuse to automatically prioritize dig and smooth/carve job types since it can break the DF job scheduler; instead, print a suggestion that the player use specialized units and vanilla designation priorities
 - `quickfort`: now allows constructions to be built on top of constructed floors and ramps, just like vanilla. however, to allow blueprints to be safely reapplied to the same area, for example to fill in buildings whose constructions were canceled due to lost items, floors will not be rebuilt on top of floors and ramps will not be rebuilt on top of ramps
+- `gui/gm-editor`: change from click to edit to click to select, double-click to edit. this should help prevent accidental modifications to the data and make zoom and hyperlink hotkeys easier to use
