Auto Placement

Thanks for the file! I still don't understand what the numbers in your picture are trying to represent (some sort of fingering information I assume) or how you are nomrally entering them - maybe also attach one of your scores created in MuseScore 2 that you are happy with.

But I can tell you that the score you attached contains a number of very strange settings that are going to cause you problems.

One is that the fingering text style "Y" offset is set very very high above the staff. not sure where you were going with that. But if the goal is to have fingerings align vertically, then you probably shouldn't using the actual fingering type for that, because they are designed to track the notes and will require endless manual adjustment. Instead, use staff text, which will sit at a fixed height above the staff. You can either enter the information for each note as a single staff text with three lines of info, or as three separate staff texts. Autoplace will automatically push each above the other, no need to manually adjust anyting at all. Or, if you want more control over the vertical height of each "line" of info, take advantage of the user text styles to give each a different offset. And use the new text intput mode in 3.0 so that after entering one text, press Alt+Right and you can immediately enter another of the same type on the next note, etc. there is no reaosn whatsoever to mess with manual adjustment of anything here.

Another issue is that the chord symbol text style is set to be so close to the staff that is is pretty much guaranteed to collide with notes and therefore not align well. I see from the PDF you attached of a MuseScore 2 score that you seem to perhaps like the chords that close to the staff and are accustomed to moving them horizontally to avoid collisions, so that's still your right although I don't recommend it. I'd just recommend not turning off autoplace in the process - just move the chord horizontally with the arrow keys as needed and leave autoplace enabled.

You also have your fingering and chord symbol text styles set not to scale with the score size, and I can't think of a good reason for that.

As for your concern about making adjustments in the Inspector while editing text, first, as mentioned, there is no reason whatsoever you should need to resort to that in the first place. But for the record, if you transfer focus to the Inspector by changing values there, in order to return focus to your score and thus continue typing, simply press Esc. Or, enter the text first before making your adjustment. But again, there is absolutely no reason you should need to make adjustments to get things to line up - MuseScore is perfectly capable of doing all that work for you if you take advantage of style settings and autoplace.

Anyhow, the bottom line is that is possible to work much more efficiently than you have been thus far. To be sure, some of that was possible even using 2.3.2, but the most significant improvements in the workflow depend on using 3.0 and taking full advantage of both autoplace and the new text input mode.
