Tablatures 1.10 has just been released.
This version features a totally rewritten copy & paste support which vastly improves the previous basic implementation. Also, when deleting a selection, everything inside it will be removed (chord texts, directions, etc…). In the previous version, only notes and barlines were deleted, but that wasn’t so intuitive or useful.
A lot of work and testing has been done, but if you encounter a problem, don’t hesitate to report it.
