QGIS plugin that adds a toggle that post-processes geometries after edit commands. Currently supports converting to curves and snapping curve midpoints.

This requires QGIS 3.14 or newer.

WARNING : QGIS doesn't support curved geometry operations, which is why by default geometries are segmentized when using features such as split or merge. This means intersections aren't geometrically accurate. The ConvertToCurve just transforms successive points back into curves for easier subsequent editing.

The most probable cause is that the tolerance to detect curves is too low. This is likely to happen when working on features that are far from the origin (large X or Y coordinates). In such a case, you can try to increase both Angle tolerance when tracing curves and Distance tolerance when tracing curves settings under Options>Digitizing>Tracing. Unfortunately, this requires a bit of trial and error, as there is no one-size-fits-all value for these settings, and, if set too high, other unexpected behaviours can arise (segments mistakenly converted to curve).

Pull requests welcome.
