I mean isn't it already that is included in the datasets? It's pretty much a mix of everything.
Obsidian is great though, even if it's not open-source. The stability of alternatives is not at the same level from what I've heard.
Mobilecoin
Anybody have any experience with mobilecoin? What is the use case for it? Seems kind of pointless and a lot more tedious than just a bank transfer. Why does signal include crypto nonsense in their app (I like crypto, but just can't see any reason why it should be integrated in the app). I'm sad that signal does not have support for 3rd party open source clients that could remove such features. Why not add support for monero instead?
If you're not opposed to apple then I would suggest getting an iPad – they are actually really completely priced compared to phones.
