A script package I've been working on with some help from @Aeldra. INIT EXITS : Sets up a number of non-standard exits, letting the mapper path to places like the prison, plaxios, tosha, and so on, as well as mapping out several bix rooms (cities other than glomdoring's, soulless and vernal) and the Divine havens. (LOAD|SAVE) EXITS : Saves all your special exits to a file so you can restore them if you have to download a new map.
INIT MARKS : Sets a number of mapper marks on places like the nexii of each city and the seal rooms. (LOAD|SAVE) MARKS : Saves/restores mapper marks in case you need to update map.
NODES (ON|OFF) : links all astral nodes in the mapper for running around during Wildnodes. ASTROBOOTS (ON|OFF) : Sets up exits for using the Astral jumping boots to get around on Astral.
MANSELINK <city> <manse short name> : run this in a manse fulcrux to set up exits leading to and from the manse from the aetherplex and the portal room of the city. Also maps the room and puts it in its own area.
In addition, it will automatically record rifts that you transverse through, so the speedwalker can use them in the future. If a rift is no longer there, it'll delete it. This also works for PATHFIND exits. (Though I haven't been able to test those as thoroughly.) (LOCK|UNLOCK) PATHS : Locks or unlocks all PATHFIND exits that it's created, in case you skillflex out of hunting.
There's a little config script where you can register bixes for the mapper to use. Has some handling for the delayed use in enemy territory/masochism dropped.
