I'm using obsidian and cryfs. Nothing has access to those except a few programs. I'm storing notes, files, documents, whatever is important and everything is synced to the cloud.

This is the beauty of it. If it works for you it's great. If this new app works for others, then it's great.

That's a good win-win situation.

As a fellow obsidian user, I wouldn't scoff at a simple app which does one thing well.

I also, myself, had a similar setup some time ago; that's super valid.
