Draw ways via pencil/touch gestures

I apologize for the title. I couldn't think of a better one 😔

I'm pretty sure this is how editing should look like on touchscreen devices ...

Is it possible to implement it?

It doesn't make sense for tracing to be the primary way of drawing lines, since most ways (streets and buildings) have straight sections connected by 90 degree corners, and tracing those accurately by hand is difficult. But I think there's an argument you could make for tracing natural features like you show.

If someday Pencil support appears in the application, then using this editing method will be very convenient for adding vegetation and rivers, as it seems to me ...

for buildings this would probably fail, but for roads it depends on the context, in many areas of the world roads aren’t straight but are following the natural topography, especially in areas that aren’t flat.

Adding Pencil support is probably the best way to get this, otherwise it requires adding a button/gesture to indicate you're in tracing mode. I was hoping to see a PR from @mormahr but I'll try add it to my list.

I was waiting for the Swift conversion to land (as your comment on my issue suggested it would be good to wait for it to be stable).

Oh, well it's pretty stable now so this is a good time 😃

Once Pencil support is working we can evaluate how best to implement this for regular touch.
