A lot of .ml users and communities are there just because it was the only big instance much earlier on. I’m in no way a tankie but still use .ml a lot (a community I run is on there) because it was the first one I made and i’m too lazy to look into new instances or switch.
On the concept of blender, I’ve been recently trying to get into Seamly2D/Valentina for pattern drafting - I’d love to see some kind of simple integration format between the two so that the FreeSewing patterns can be easily loaded into Seamly2D instead so the measurement files can be used from there and the pattern tweaked.
