With Apple Pencil 2, we can now tap the pencil for certain use, e.g. change to eraser mode in Notes.
I believe this can be very useful for uMake. One that I often need is the lasso mode. I like to design on my bed and find that having my other hand to hold the lasso button is sometime a bit hard to do.
My initial suggestion is to have the lasso mode being locked instead need to tap n hold, but it would be much better if we could use the Apple Pencil 2 feature for this.
It will be even better if the pencil feature also have several options, e.g. switching Apple Pencil on/off, changing current view (rotating from front to top,etc.), open up options/menu mode, etc.
