Nice, I just learned about the Zoom plugin from your video. I like your feature idea that it should include the ability to browse one level up. I noticed it is one of the feature requests already logged in the project: One-level Zoom Out · Discussion #28 · vslinko/obsidian-zoom · GitHub
You mention how it takes work to setup the plugins you want to use, such as Templates. I think this was a good decision, since there is no single “proper” way to use Obsidian, it makes it easy to customize to your tastes and keep Obsidian very simple if you choose. Likewise, with Vim and Emacs, I keep fairly basic features only.
13m12s: Syncing settings is a feature that was added in 0.12.8 Obsidian Release v0.12.8
(Though I haven’t tested it myself.)
