I've been using the paper-based Bullet Journal for around 2 years now and I want to have one in the cloud.
There are some apps that try to be the BuJo in the cloud, but I consider them unusable. Their UX is over-bloated. Adding a task, for example, needs too many clicks for my taste.
On the other hand, the apps like Notion or Obsidian don't work for me, as they have too many features that make it hard for me to use them rapidly. Shall this be a database? How shall I render that? Should I create new page for this project? Or put it into a table? etc.
