The UG tabs were great for motivation and mixing things up, but the basics will never change. Unfortunately a lot of learning any instrument is monotony and practice. You're going to have to work through that if you want to pick it up again. Without tabs to lean on I've just found it fun to noodle around with impromptu riffs and see what comes to me.

I was a bit lucky I guess because I worked myself a bit more solidly into the intermediate range and my fingers still remember all my chords. I just don't have the same finger stamina and my chord transitions are a lot sloppier. I'll just be happy when I can jump back into a nice fingerpicking flow again though.
