You are probably correct. Many/most Mac users have an iPad or at least an iPhone. But neither is of any use here, if you want you use your big 43 inch external monitor.
Would be nice if there was a way to use iPad/iPhone either as the the viewport control device. Not having to buy the space mouse.
Kinda like the https://www.remotemouse.net/ but tweaked to work with Shapr. So a trackpad area that works changes view as on the iPad and with shortcut above.
And I’m sure I’m not the only one having a Magic trackpad in a box somewhere. Would be nice if Shapr would recognise that as a 3rd/separate input device, so it does the view control and don’t just become another mouse… That’s not the case today, is it?? Looking in settings, it seems you still have to use shift/cmd/opt keys to zoom/pan with the trackpad. Like if you only have the trackpad (on macbook)
