Choosing which way to continue is difficult

[bborkmiller]

If two ways both terminate at the same node and I want to continue one of them, I can't tell how to pick which way gets continued. iD seems to choose for me, and it doesn't always choose the correct one. If I'm missing something obvious, please enlighten me.

Yeah, it just chooses arbitrarily right now. I'm going to change so that the line draw tool always starts a new way, and the way you continue an existing line is by a "Continue" menu item when clicking on a vertex (#560). Disambiguation can be done either by drawing a new line, then merging it with the desired existing line, or multi-selecting both a vertex and a line to continue and using the "Continue" action.

Cool, thanks for the response. FWIW, I would prefer something like the second solution. Going back to the old line to select it and merge with the new one can be cumbersome if you're tracing a very long way. Perhaps if you have a line already selected when you choose the line tool, it goes into a "continue way" mode beginning from the currently-selected way?

This has been implemented; you'll be able to check out how it works on http://openstreetmap.us/iD/master/ shortly.
