MuseScore 3 chord symbol layout is poor
See, using full default:
All chord symbols are at different height making it difficult to read, and sorry I can't stop thinking, ... just ugly.
That auto-layout will change the height of some chord symbols when necessary is clear, but hopefully will do so only when a chord symbol needs to be put much higher than normal. In a case like this one when the difference of minimal required height between all the chord symbols is very small, they should all be aligned to the highest one. (at least by measure)
