I use both of these, but I think they're stupid. I don't want some harebrained sync-to-browser-by-routing-through-my-phone-after-scanning-a-QR-code scheme that breaks whenever my phone is offline, or when I need to borrow a computer, or when I'm in a different country... I want a bog-standard client-server architecture with a fully featured client on my phone, desktop, and browser. Everybody did this in the 90s, it's not hard... why has it gone out of style?
