Anyone (guitar players) familiar with this program and what it's purpose is? I know, I could google it and read about it I guess, but I was looking for firsthand experience. Pros/cons?

No idea.

Nope. But I'll ask my son.

Composing.

You can write your own tabs with it.

You can play along with midi files.

I've got GP5.

Thanks.

I *stumbled* on to someone's website that has tabs for a bazillion songs, but they are all GP5 files which means...you'd need GP to view them. Of course, that would be the least of my problems. The biggest issue(s) would be that 1, I don't read music, 2, I don't play guitar, therefore, reading tabs would be like reading a book in chinese. LOL ...but maybe someday I take up geetar.

^if you do this is a great learning tool.

The software is a great tool for learning guitar, the tabs, or both? I assume the tabs are a great tool because when I see a Youtube video of someone playing guitar people are always asking to "get the tabs."

http://www.ultimate-guitar.com/  has all these types of tabs 1000's of songs.

GuitarPro is a great tool for practicing. You can slow down the tempo to help you learn new songs. And you can print out the tabs too. it's really great.

re 7: Both. Of course, you want to get a little finger strength going with the proper exercises additionally or you won't be able to keep at it long enough to learn anything but GP definitely breaks things down into easily chewable pieces.
