Yes, you are right, I mixed that up. >> This will also create undo/redo problems, since undo/redo in math goes >> through the text representation. > > I could not discover any. Do you have some example? No, this is so far only a theory based on past experiences. I expect problems in the following situation: - do something that you want to undo (e.g. cut). The cursor must be in a brace inset that will not be restored after undo because of the removal of superflous brace insets. - undo Now you will either get an assert, or a warning on the console that the cursor is broken and will be fixed. I don't know if such a scenario is possible in reality, but what I know is that asArray(asString(ar)) == ar should hold for any MathArray ar. That is not the case if brace insets are removed. Georg
