When will you improve your Guitar TAB input?

With Guitar Pro, MuseScore and Sibelius all have the ability to click on a line and start typing numbers, you can also navigate with the arrow keys.

e.g. The first 3 notes of a G Major Scale, click on the sixth string and type 3 --> 5 --> 7

You already have a qwerty input mode, I would like to see this as a mode for TAB input, I'm sure many other guitar players would also like to see this.
