I've used Obsidian for two years, and these days mostly through a terminal,
which means I only see the plugins it's most known for on mobile apps. The only
plugin I need, or the only reason this is still an Obsidian vault and not just
a git repo of markdown files, is Dataview. I use a version of Zettelkastken
reliant on a filename prrefix system that I navigate with tags and Dataview only
on the mobile GUI.

* 000: config files
* 100: fleeting, to be indexed/renamed
* 200: permanent, mostly lists
* 300: drafts; published/exported writing goes to 350
* 400: databases sorting 200 and 300

Across devices, I use:

* iPadOS: app + Working Copy
* Android: app + Termux
* Linux: vim with a markdown ftplugin, mdt-tui for terminal viewing, and

$ git commit -m "$HOST_NAME manual backup $(date '+%F %T')"

My phone and iPad have Obsidian Git, but I keep running into problems with it
and so externally troubleshoot with Working Copy or Termux with such frequency
I'll likely uninstall the plugin entirely. My main annoyance is the lack of SSH
support on mobile since I find git tokens extremely annoying.

Dataview is useful because I create data-type notes: Russian flashcards and
birth charts, both of which have template fields like part of speech and gender
for Russian, or rising sign and other placements for astrology. In terms of
logged hours, I primarily use this vault for writing first drafts that are
exported to other formats for editing and publication. Dataview helps on the
mobile apps because I don't use subfolders, but instead see dozens of notes
prefixed "list-" or "outline-" or "recipe-", for example. On mobile I never
expand folders 200 or 300, but anything I jot down quickly ends up in 100, per
Zettelkasten's "fleeting" designation. These prefixes work out great in a
terminal, though, and simply hitting "tab" for all possibilities does a lot of
filtering.
