List map names when using the "maplist" command
The "maplist" command currently lists all maps by describing their id, WADs and map number. If the maps' names were also listed (e.g. "MAP01: Entryway" instead of just "MAP01"), it would make searching for specific maps in a large map pool significantly easier, for instance.
The main problem with that is that Odamex will need to open every wad after loading the configuration (or midgame), load the mapname according to the Mapinfo, and close it.
Besides, many wads could have MAP01: Entryway as the mapname, while the level was named differently according to the texture used in the intermission....
Would that be too much of a resource hog to be feasible? Also, what you said later is mostly true for old WADs, but almost every mappack that's more recent and modern has MAPINFO or DEHACKED map names, so I'd say it's still vastly more useful to be able to see the defined names than not.
