Interesting! I thought it would be clear from the context clues of plugs everywhere but perhaps not. I think the generator plug could have been more obvious, I guess at the moment it just looks like another cable like all the others. But as it's the first one you pick up I hoped it would be clear it was different.
I completely agree that when cables get behind bushes it's hard to see. My solution was going to be to have that selection glow appear in front of everything but I ran out of time. It was next on the todo list!
Thanks for letting me know!
