I don't see this mentioned in the manual or anywhere else and there's a few related things I want to mention. It sort of came up in another thread.
Once we have Drag-Select, will the program have it's own clipboard buffer? Could I, for instance, open one map and select a room and it's contents, cut it (ctrl-x), and paste it into different map?
Related to that, is there a plan to implement various keyboard shortcuts for selection? Such as holding Control while left-clicking to select/de-select various objects? Like how Windows would handle file selection in an open folder.
