Necroposting, but I have the same problem on MacOS Ventura 13 with a touch pad. On the plan display, two-finger-drag moves WAY too fast, and command-two-finger-drag zooms WAY too fast. (Motion in the 3D view seems fine.)

If I could cut the sensitivity by about a factor of 5, life would be great. (Yes, I could use keyboard shortcuts, but I'd rather control fluid movement by using a fluid input tool.)

Are there any behind-the-scenes configuration variables to change this?
