At home my systems use Star Wars planet names like Naboo, Coruscant, etc.

At work we use Game of Thrones characters (and we’ve somehow exhausted that list…)

I’d go with either Firefox or Thunderbird. Both are immensely useful pieces of software that I use on a daily basis, and have evolved (mostly) nicely over time.

Not to give Mozilla too much credit, Nextcloud is also pretty slick!
