I came here to post about this too. I wish the selection distance was much smaller when using the Apple Pencil. For a finger it feels pretty suitable, but often i'll be using the node tool to try to adjust the curve of a line and instead it will select and move a control point. I have to zoom in to pretty extreme levels to be able to adjust details like that which are much easier to manipulate on the mac Designer app with a mouse. Maybe the selection distance could be configurable individually for finger and apple pencil to allow some amount of adjustment for users who have less or more dexterity too!
I've only been playing with affinity designer for a couple hours on iPad (I'm a big fan of the Mac version!), and aside from some little glitches here and there, this is the main thing that's been annoying to my workflow. Otherwise, seems like a really great app. Looking forward to seeing it evolve and gain polish!
