Segmentation
First off, I'd like to congratulate you on the Musescore software. It has helped me arrange and re-arrange a lot of pieces.
I do have a slight complain though. In the previous versions, there was an option in segmentation called trailing space. This is missing in this new version and there is only leading space. While either one can be used as a substitute for each other, the Leading space seems to be nullified for barlines even after I save multiple times. This is quite a problem, since then, the spacing according to the value of the last note is not correct, resulting in a visual problem (the spacing after a crotchet and a dotted minim becomes equal). It would be brilliant if you fixed this problem, or bring the trailing space back.
Musescore 3 is working brilliantly, and this is the only problem I have faced so far.

+1 to bring back Trailing space as a property
In MuseScore 2 I found the Trailing space very useful when notating alternating time signatures. The second "dummy" time signature is visual only and has no effect on playback or measure length. Measure length has to be adjusted manually.
It is possible to notate the same thing in MuseScore 3, but I find it much more tedious to get the spacing correct when only the Leading space property is available.

The problem with leading space not being saved for barlines is known and will hopefully be fixed in a future update, see #282899: Leading Space is resetted for bar lines, when reopening a file that has been saved with MuseScore 3
