Add square brackets to score elements to indicate editorial additions/changes
The standard method of indicating editorial additions and changes in a score is to enclose them within square brackets. It is possible to do this for many elements in MuseScore by editing an existing element or by creating a text-only version from the symbols pallet. However, this is a bit of a kludge and is impossible (or very difficult) for elements such as slurs and ties.
It would be useful to have a facility to select an item, or range of items, and to surround it with square brackets.
