I’ve been using Resolve on Ubuntu and after a bit of a bumpy start it’s working just fine.
FreeCAD got a 1.0 release late last year. I need to try it again. I might try one of the browser based CADs, but the idea grosses me out.
The one substitute I’ve yet to find is for Photoshop, so I need to run that through a VM. It annoys me that nothing compares. I respect Gimp but the UX is overtly terrible. Krita has similar issues for photo editing but is slightly better. Affinity Photo doesn’t run on Linux.
I enjoyed it more than Krita. I find the UI more intuitive and closer to Photoshop, which was my #1 (at least for CS6). Photoshop remains the only piece of software that doesn’t have a reasonable subsitiute or Linux client.
