Apps - Photo editing and 3D CAD are the main areas I’ve struggled with on Linux
Yeah, I feel that. Paint.net is the sole reason I still fire up my Windows VM every now and then.
The closest you can get is Pinta and even then, looking at the surface things may seem very similar, but the workflow is totally different (it doesn’t even have overscroll god damn it!) and the plugin scene is deader than dead. I wanted to code a proper replacement based on Pinta, but I haven’t got the motivation or time for that.
If I wanna edit an image, firing up a VM is still genuinely faster than trying to work with Pinta or GIMP or any other opensource alternative for that matter. Krita has surprisingly been pretty good at replicating the workflow, but it still falls short.
