I know how you feel. I find the infinite monkey approach helps and if, after infinity-1 attemps to figure out a component, you still can’t understand it then try a different approach.
There was a good path mapper example somewhere… It was a video tutorial done by David I think. I can remember not being able to find it last time I searched. I can also remember thinking it made perfect sense when I watched it but then still couldn’t use path mapper so gave up again!
There probably is a good example of each less obvious component but no one has ever put them all in one place. Follow this link for a good google search of the old forum… Search Old GH Site topic Someone posted a link in that topic.
The search on the old site always made me feel like I’d just put my glasses down but couldn’t see where I’d put them and then they’d be right in front of me. I do that a lot anyway though so maybe the old search was great.
