The only documentation I can find describes inserting bars BEFORE a selection or measure. A big, PITA when a piece has a lot of metric changes, cross-measure ties, etc.
One example: A piece contains a 7/8 section followed by a 4/4 section. How can you extend the length of the 7/8 section by one new, blank measure in a single step? Docs describe only ways to use the bars popover, etc. to add a measure of 4/4 between the two sections – or to embed a measure of 7/8 inside the 7/8 section.
What am I missing? Some sort of Insert Mode workaround?
