I used substance designer on a laptop for the first time today and it is HORRENDUS. It's actually impossible to navigate without a mouse remotely comfortably.
Why is every program like this? Does no one use laptops anymore? Cause my god. We've had fantastic track pads on windows for like 10 years now and every program is stuck in the early 2000's. This is why people move to tablets no one cares on PC.
Please, please make this work properly with trackpads, and touch while you're at it. Programs like these NEED decent navigation.
Use blender as an example, navigating it's nodes is a DREAM on a laptop. It's fluid and just works how you expect.
