I started with GIMP and still pull it up first before worrying about Photoshop. For me, the "fighting muscle memory" comes from "huh, GIMP does it like this..."

I think it might be muscle memory. I started using GIMP in 2005 or so before the single window mode, and my muscle memory is tailor-fit to it. It felt like an extension of myself.

With GIMP 3, there are a lot of improvements! But it also breaks my muscle memory a lot. GIMP 3 is objectively better, but I find myself opening 2.10 regularly.

How do you wanna complain if you dont know anything else?
