HP-41 extended memory file types

This was added on by the CCD module. According to "Extend your HP-41", the following mappings are used by the CCD module:
4 - matrix
5 - I/O Buffers
6 - Key assignments

In the AMC_OS/X I followed the CCD scheme above, plus defined a few other types for the following:

7.- "T": Status Registers backup
8.- "Z": Complex Stack from 41Z
9.- "L": LIFO File for Doug Wilder's LIFO functions
10.- "F": FORTH Code backup
11.- "H": Binary Stack backup from HP-16C

The enhanced CAT" 4 shows the file types letter for all the 11 types in the display during the enumeration.

5 - Key assignments
6 - I/O Buffers
I kind of wonder why it is swapped in my code, as I got the matrix at the same position (4).

Is there a comprehensive list somewhere that shows all file types that have been defined somewhere by the community?

Do we have a need for additional file types? (ROM compressed, ROM uncompressed, WALL, others?)

I wouldn't use a swapped-numbers convention for KA and Buffer files, that would be a big problem in the code checking on the file types, and very confusing to the users as well of course.
