Observed behaviour column widths return to default narrow setting:

as additional note it would be cool to be able to put horizontal lines here to separate different command groups.

Thanks to your detailed description I can reproduce the problem.

This problem is supposed to be fixed in XnView MP 1.8.7. Please check and confirm the bug fix here.

seems fixed.
