Non-collision auto-tracing [Feature Request]

[oanegros]

Hi,

Could there be a possibility for a one-click and semi-auto tracing preference setting which disallows entering a previously traced region (or x µm tube around previously traced regions)?
This would be very useful for our use case where we have non-overlapping traces that can look adjacent, especially for time-tracing and other un- or less supervised bigtrace applications.

Thanks!
