Learn the blues scales, they will help you "widdle" all over the place.
Also you could try retuning your guitar to a different tuning. Something like DADGAD is fun. But dont look up how to play chords in that tuning. Just mess about making your own chords up.
Your at a major turning point in guitar playing. Its a big step to stop playing them chords but its great once you get it.
Have you tried to learn to finger pick yet? That maybe fun for you to have a go at.
Try finding some tabs too. Try something like Castles Made Of Sand by Hendrix. Its not easy but it will give you a crash course in blues scales and ways to not play chords. Also once you've mastered it you will be able to show off to your friends.
Castles Made Of Sand also gets you in to playing chords with a bit of widdle, if you know what I mean.
Good luck and keep it up.
