Sketcher: normal/construction geometry status is remembered

Is there an existing issue for this?

• I have searched the existing issues

Problem description

When construction geometry is toggled on, and the sketch is exited, and the same or a new one is opened, be it in the same file or not (even a new file), construction geometry is still toggled on. FreeCAD remembers the status at program level. While the behavior can be understandable if the same sketch is opened again, it is unexpected and surprising because it is unique in the CAD world. Normal geometry is the most commonly used in sketches, and should be the default when creating a new sketch or opening an existing one.

Proposal:

1. Normal geometry is toggled on for newly created sketches.
2. Sketches can remember the geometry status when closed (each sketch has a parameter, not at program level), with a checkbox in settings (“rembember if construction geometry is activated” or similar).
3. By default, FreeCAD doesn’t remember if construction geometry was toggled on, thus normal geometry is always active when a sketch is opened.
