Suggestions by @JulienKaspar

Outliner: Use interaction mode to restrict syncing

Use the current interation mode to prevent syncing from getting out
of sync. Because the bone elements shown in object mode are not the
same elemens as in pose or edit mode, it is necessary to only sync
bones in bone edit or pose mode.

LANPR: Smooth contour modifier file.

LANPR: Smooth contour modifier name change.

LANPR: Render status.

LANPR: Remove update button in GPencil LANPR tab.

LANPR: Merge error fixes.
