I downloaded the app months ago for my Mac but honestly forgot I even had it installed until I read this thread. I use the website every day just fine. There’s no need for the app.
I use Linux, am a heavy Notion user through the web app and I'm very happy. I'm not sure why people would want the desktop apps (I do use the android app for a bit of on he go reading and adding images).
Yes it matters. I could write a WebKit2 wrapper for the webapp in 10 minutes just so I can treat it a like a standalone app and not just another tab.
If it's electron, give me linux.
