I just signed up with guitarmasterclass because I wanted to learn the Jimi Hendrix Rhythm style lesson by Diego Budicin. I like the lesson a lot, but if I had known that all the tabs on this site are shown in this ugly confusing character style I would not have signed up.
Why don't you show normal tab? It's 2015, not 1980...
And why don't you just put stems in the tab to show the rhythm? Then you have the best of both worlds - you understand the rhythm at first glance, and you know where to find the notes, but you don't need the music notation.
edit: ok, I should stop ranting, just discovered that you can display the tab with TuxGuitar. :-)
But it would be nice to see the tab in "non-character style" directly in the lesson window.
