Hi @konradh, to easily reestablish the full 4/4, activate insert mode (I), select the first 4/4 and click twice on Enter (once to “edit” the 4/4, and once to confirm it). The needed rests will be inserted, thanks to activated insert mode. Deactivate insert mode when finished!:
Then you can delete the second 4/4 (because redundant).
Depending on what follows, and if the rests are needed, or the following music should be moved to the first 4/4 bar, the methodology may vary.
