I searched for this, but did not find what I need. Sorry, if it has been discussed already.
I want to move rests to avoid collisions of very simple type (see the attached PNG image). I thought I can simply go to Engrave mode and start moving these stubborn guys, but could not do it. What is the secret here? Thank you so much.
You can move rests vertically right now. You will be able to adjust the horizontal spacing of rests (and also notes) in the imminent version 1.1 upgrade - and that will also give finer control over vertical positioning of rests.
In the current version, open the Properties panel (Ctrl-8) and switch on the βRest pos.β property. 0 is the center line of the staff. You can change it in increments of one note-position.
