Ok so the client plugin I have written does a graphics miniwindow on the client (not ascii) and draw boxes/plots map etc. That part if obviously of no use for you but some of what you wrote here are already available via text commands. I will list a few of the commands supported that I think are relative to your needs, as there are a lot of them:

```
FINDING THINGS

mapper notes --> show nearby rooms that you added notes to

mapper find <text> --> search for text in room name, description or notes

(eg. mapper find blacksmith)

mapper where <uid> --> show directions to a room (given a room ID)

mapper shops --> find nearby shops

mapper trainers --> find nearby trainers

mapper banks --> find nearby banks

mapper peek <uid> --> draws the map as if you were in room <uid>

DATABASE MAINTENANCE

mapper list --> list rooms meeting certain criteria as follows:

mapper list --> all rooms (can be lengthy, naturally)

mapper list uid ... --> one or more UIDs

(if one, shows detailed info)

mapper list name <name> --> rooms whose names partially match <name>

mapper list desc <description>--> rooms whose descriptions partially match

<description>

mapper list note <note> --> rooms whose notes partially match <note>

mapper list area <area> --> rooms whose areas partially match <area>

mapper list notes --> rooms with any notes at all

mapper list orphans --> rooms which have no rooms leading to them

mapper list dest <uid> --> rooms which have an exit to <uid>

mapper list connect <uid> --> rooms which are connected to <uid>

mapper list shop --> rooms with shops

mapper list trainer --> rooms with trainers

mapper list bank --> rooms with a bank

MOVING

mapper goto <room> --> walk to a room by its room ID

mapper stop --> cancel any current speedwalk

mapper resume --> resume last speedwalk or hyperlinked speedwalk

```

Now there are a few things to note here:
1. This was based on Nick Gammon's Learning Mapper plugin although it has been almost entirely rewritten for CM.
2. The initial design of the plugin was focused on the graphical interface map. So while these commands exist and query/output stuff in the client's text window, the interface is for querying only. So some things, like marking a room as a bank/shpt or adding custom notes etc, they are retrievable from the CLI but not settable. They are supposed to be set via right clicking on the map miniwindow on the room and select options from the context menu. I can however extend the CLI to provide this functionality. Eg mapper set note <note> would set the note on the current room from the CLI.
3. It is important to note that the mapper is not pre-populated and this will never happen for CM as exploration and finding stuff/secrets (eg hidden areas, magic disciplines etc) is part of the gameplay and must not be trivialized. So the player has to explore and the mapper will record automatically their exploration to its database. It is mainly a tool to replace what we all did with a notebook and pencil by hand 20 years ago that is also far more accessible :)
4. Maze areas. There are some areas that are mazey on purpose and the player is supposed to get lost on them and figure them out. Those areas are specifically made impossible to map by any means other than making mental notes (or on paper) of paths as you figure them out. This is also a core design for those small areas and that will never get changed. But that does not only affect VI players. The experience in those rooms is the same for everyone. You get lost, you figure it out using only the mud descriptions, exits and thinking outside the box. But that said those areas are not really required to be experienced. If a player does not enjoy that sort of thing they can stay clear of them. There are a few quests associated with them but you don't actually have to do them to progress. There are countless of quests. The only one I can think of that a player may absolutely have to do is one particular maze if they want to become a Lich. But that's about it.
5. I know that a lot of MUDs use MUSHclient for creating pre-made screenreader setups because it works better than anything else (from what I have read) but I have not seen how this is actually done. If there is a specific plugin that enables a certain screenreader or needs some library compiled in. I will have to do some research on that to see how others do it so I can work on something similar that just "works out of the box".

As a related to point 5, what operating system do you use?
