Hello David,

• Why can you plug a module into a page that already has one? That was the fundamental problem that Namir had. I would have preferred an error and the need to unplug the previous module first.
Nothing prevent you to do that, as long as you do not unmap one of the YFNZ/YFNX module, then the PLUG functions are no longer there, this is what happened to Namir in 2014 and to Uli this week.

Test case: (note: by design, virtual module take precedence over physical ones.)
Code:
            // assuming no physical modules is inserted into the 41CL MMUDIS      // disable MMU MMUCLR      // clear MMU configuration "YFNZ"      // 41CL Extra Functions PLUG1L      // map ROM to page 8 MMUEN       // enable MMU CAT 2       // "-YFNZ 4G" "MATH"      // Math ROM PLUG2L      // map Math ROM to page 10 CAT 2       // "-YFNZ 4G" and "-MATH  1D" "STAT"      // Stat ROM PLUG2L      // map Stat ROM to page 10 (and unmapping Math ROM at the same time)  CAT 2       // "-YFNZ 4G" and "STAT  1B"             // OFF, insert a physical module into port 2 (I used the Home Management ROM), ON CAT 2       // "-YFNZ 4G" and "STAT  1B" (virtual ROM) UPLUG2L     // unmapping Stat ROM from page 10 CAT 2       // "-YFNZ 4G" and "HOME MN 1A" (physical ROM)             // OFF, remove the physical module (Home Management ROM) from port 2, ON CAT 2       // "-YFNZ 4G"

• I wish there was also a "PLUG" command that plugged the module into available port.
Not as easy as it sound, but it could have been done.
ROM file format does not include contextual information as to which page and in what bank it must be mapped.
MOD file format does have that information.
41CL DB ROM have most of that information thought.

• What's plugged in where?
As Mark said, all CCD ROM implementation has the CAT 8 to F allowing you to catalog a specific page.
Also, several modules (ZenROM, HEPAX, etc) has a ROM editor that allows you to see what's in any page.
But I agree with you that it would have been a great function to be included with the YFN? ROMs.
I could probably create a small FOCAL program that extract the mapping information from the 41CL configuration space, let me have a look.

edit 1: typos
edit 2: change the physical ROM to Home Management ROM to remove ambiguities
