There's a line of products I've been working on the past few years. I didn't create the original files and there's a lot of things I think could be improved upon or simplified. Also every customer wants a slightly different variation and those files weren't really set up for easy modification, so it's been kind of a mess to deal with. Well, right now I'm working on the next generation so I get to make it exactly how I want it, and it feels so satisfying to make it the way i feel is right.
