Obsidian is only seven people but we are working on this from all three angles:
1. Make community plugins less necessary over time as basic features become part of core
2. Improve the security of community plugins
3. Make it easy to create your own plugins that you can fully trust, e.g. with the recent release of Obsidian CLI
If you can build in one thing, I'd pick something equivalent to Omnisearch. That makes it much easier to find things. I always struggle with the default search.
True the default search is really good at not bringing up what I'm looking for. It's the #1 improvement point for me.
