Sibelius-styled visual display.
Including:
- Numbered strings at every system.
- Tuning text at the start.
- Rhythm in the tab notation.
- Tab symbols covered in white to heighten the contrast/increase visibility.

I'm not sure if I like having numbered strings, but I suppose that could be a non-default option.
Having rhythm in the tab notation would be useful for #48
The numbered strings are a useful reference for beginners, but yeah, I don't feel so strongly about it. I feel like it's okay to put up some ideas that might not make it into the program if just to stir discussion about features and their utility.
Definitely agree about 48. The lack of rhythm in tablature notation is it's biggest weakness, I think.
I agree, and I suggest taking inspiration from TuxGuitar's interface, that I think it's very clean and readable:

so:
- lighter lines for the tab and the staff
- a slight white border for the symbols in the tab (as suggested by Canaanabolaanan)
- rhythm displayed outside the tab, to improve readability
what do you think?
I definitely like the lighter lines and white outlines.
Having rhythm displayed outside the tab looks a lot better than the Sibelius tab notation IMO. I think it should definitely be optional, though
Definitely a good idea. Would it be workable with more than one voice on a stave? Would you have stems on top and underneath the tab?
Also, the resize option for the stave on the existing PT is useful as I teach someone who is visually impaired and have to enlarge the stave and fonts on the printouts for him. The option to remove the standard notation means there is less printing involved.
It's good to see my example back.
Tuning Text at the start means a uge decrease of errors in new transcriptions: the Tuning Information is always correct (and standardized). It would be a lot easier for the moderators.
Indeed the string numbers are very useful to beginners. I don't know how it works outside the Netherlands, but we use a Mnemonic to memorize the stringnames: Een Aap Die Geen Bananen Eet. Unfortunately it works backwards from string 6 to 1.
25 Years ago I tried to introduce a memory aid in the right order, but every time my students would stumble on a good willing neighbour: I never got rid of the Monkey. To prevent the confusion, I gave up. The only change I make is that my Monkey doesn't eat 'Brood': Brood or Bread is a one syllable word, better for really young children. Oh, and then I warn them for the neighbour, and say that bananas work as good:)
Also lots of starters read the tab upside down. In the first lesson I sometimes keep the tab in the vision of the student looking downwards over the guitar to show that they read it as they see there guitar (Sparrow view - like standing on the Eifel Tower and look downwards). Then I change a few centimeter higher than horizontal to show that they fool theirselves.
I definitely like the rhythm in the tab, but a disadvantage of Sibelius is: there is no difference between quarters and half notes, also harmonics and whole notes are not visible. Simply because noteheads aren't visible. So IMHO the most perfect solution would be rhythm with noteheads underneath (low melody and single melodylines) and on top (high melody) of the tabsystem.
And of course the notes in a White Room would definately be the Cream on the Pie.
