Two Bugs with Instrument Changes
By "changing insturments" I mean the action of double-clicking on an instrument-name in your score (or using a shortcut of which i'm not aware), then clicking on the "change instrument"-button, then changing your instrument to something else. (for example "Violin" to "Cello")
Usually, when changing something in your score, an asterisk * will appear at the end of the name of your score in the tab/window heading. This indicates, that there are unsaved changes to your score.
When changing your instrument this * simply doesn't appear. The score simply doesn't indicate that there have been changes.
(Adding a new instrument triggers the * to pop up, as it should do. Changing instruments lacks this important feature.)
Changing an instrument can't be undone by pressing [CTRL + Z]. Nothing happens.
(Again, ADDING a new instrument can be undone. It's just the changing of instruments that lacks this important feature.)
