I just submitted PerfectGuitarSongBook version 1.4 to the App Store Review Team.
The new version will as usual make PGSongBook even more perfect, with an overall graphical overhaul, great new features and tons of bug fixes.
Here is a screenshot of the new UI in comparison to the old one:
Looks great, doesn't it?
From my experience, it takes about a week for the App Store Team to review new updates, so if there is no problem, you all will soon be able to explore it.
A full list of changes will come soon.
