 The following applications are not needed. I alternate between trying to /stay in Emacs/ taking advantage of the consistent interface, and using a stand-alone app on my Workday computer.

 * RPG DM
 Been working on my [[https://gitlab.com/howardabrams/emacs-rpgdm][RPG DM project]] for getting Emacs helping as a /Dungeon Master's Assistant/. The idea is to be able to roll dice and whatnot. What I find most useful is the [[https://gitlab.com/howardabrams/emacs-rpgdm/-/blob/main/rpgdm-tables.el][random tables]].
