Suggestions for amendments to the engraving of guitar tablatures

My idea

In this issue, I will propose some corrections to the engraving of guitar tablatures. The flaws were revealed by me in the process of writing a recent weighty transcription. This time I will have to deviate from the standard template, otherwise I would have to spam several issues in a row. Therefore, I decided to put the minor flaws together and report it in one issue (I hope the MuseScore Studio team will forgive me for this).

Problem to be solved

Below I have described point by point what each flaw is (in my opinion).

1. Improved staccato articulation position in guitar tablature.
   • I propose to improve the staccato articulation positions in guitar tablatures so that they align in the same way as the tenuto (i.e. eliminate the strict rule that such articulation should always be strictly outside (above) the tablature).
   • I honestly don't know if this is a bug, but I think it's probably true.
     In accordance with the rules of engraving, articulations such as staccato and tenuto are allowed to be placed within the staff as close as possible to the notehead/stem (note: tenuto is aligned according to such rules, unlike staccato).

   • Also, please pay attention to the staccato in the reverse bends. In this case, it would be more reasonable to place the articulation under the fret number:

2. Alignment of the fret number positions in the tablature according to the position of the grace note.
   • I propose to amend the horizontal alignment of the fret numbers in the tablature in cases where the positions of the numbers from which, for example, the bend begins, should be strictly under a grace note, and not under the "parent" note.
     It would also be nice to reduce the size of those numbers that relate to a grace note.
   • This way the tablature will become visually easier to read. The user will clearly understand that the fret number refers specifically to a grace note.

   • This applies to pre-bends and unison bends.
3. The let ring lines should cover the full visibility of the note duration, not just the notehead.
   • I propose to ensure that the let ring line is stretched for the entire interval after the note (i.e. not so that it ends only at the note head).

   • This will allow the musicians to more clearly determine at what point the "let ring" technique should end.
4. Release back to 1/2, etc.
   • 
   • In my opinion, this is incorrect. The bend digit should not be located within the tablature, only the fret numbers can be in the tablature.
   • Take a look at how this is indicated in other notation software. I think this is the right thing to do:
