If I could make a feature request: it would be really nice to have a (default) property that multi-rests automatically stretch to accommodate any objects (in particular tempo markings). I feel I’m spending far too much time resolving collisions in parts between tempo markings that are many bars apart, often aggravated by further collisions with rehearsal marks. Ideally, this would then be a property (of the tempo marking) you can switch off, though even that without it would be an improvement (you can always overrule the horizontal spacing).
A somewhat related secondary request would be to have an engraving option that the width of multirests is treated the same, regardless of the number of bars multi-rested. At the moment, the behaviour is for long multi-rests to get more space than short multi-rests, a behaviour that I personally don’t find aesthetically pleasing nor convenient.
