Continue drawing lines and areas from a mid-point #8088

Closed DujaOSM closed 3 years ago

DujaOSM commented 3 years ago

Drawing lines and areas from scratch is intuitive and easy -- just go clicking on the map to define successive points. However, if you have to adjust an existing line or area, the process is much slower: you have to double-click the line or grab an arrow on it to define a new point and move it around, then repeat for every new point - a lot of RSI-inducing mousework.

As an usability enhancement, it would be nice to allow "continuing" existing lines and areas from a mid-point (using "Continue" from context menu or [A] shortcut key). As the result, the selected point can be moved, and any subsequent click would define a new adjacent point, connected to the neighboring points (just as in the current Area drawing mode).

Currently, I can achieve something similar by cutting [X] the line, then continuing it [A], drawing as much as I want, and connecting it back near the cut point. That, however, is not always feasible due to relation breaking, and may produces some side-effects such as converting areas to multipolygons.

There are obviously details to work out, but you get the idea...

@DujaOSM This is a neat idea. I'm not sure how it'd feel in practice but we can look further into it. This and #2272 would probably work the same way.

DujaOSM commented 3 years ago

Yes, this is basically a duplicate of #2272 (my search failed to find it), and there are several ideas I like, particularly the @slhh's neat video. The video is probably the best illustration how it should work, perhaps only differing how the action is initiated. There's still an open issue as to direction...

Okay, I'll close this in favor of #2272.
