I have just started using Tuxguitar to write some TAB from some scrolling YT clips. Interestingly, it writes standard notation as you enter in TAB. It is much easier for me to use than Guitar Pro. I couldn't get the hang of that somehow. I had to pay for it too. Tuxguitar is free.
I wondered if there was any love out there for Tuxguitar.
PS: I should mention that this is on the Linux platform
