I have a couple of problems with the read-only function.
"What is new in LyX 2.2?" (http://wiki.lyx.org/LyX/NewInLyX22#misc)
states that
* It is now possible to toggle the read-only state of a document via the
menu Document→Disable Editing.
However, I cannot see this is in 2.2.2.
Saving a document as read-only seems not to work properly. Maybe this is
already known.
1. Toggling read-only (buffer-toggle-read-only) does not render the
document dirty. So it is not possible to *just* make a document
read-only and save it.
2. When opening a document saved as read-only it always opens as
non-read-only.
