Pro Flexible hierarchies
Dendron makes it easy to create and refactor hierarchies at will.
Pro Powerful built-in publishing
Dendron ships with a configuration for publishing your notes with 11ty. The resulting site is searchable and easy to navigate, and the VS Code extension can easily place links to notes in your clipboard for rapid sharing.
Con Interface can be confusing
There is a fair amount of flexibility to the interface but it can also become confusing, especially when some parts are not necessarily simple to use. Most of the basic features nevertheless are intuitive.
Con Database storage rather than files
This makes it a little less simple to work with (also has benefits).
Con Not markdown
It will import and export markdown but it does not store content as markdown. This isn't necessarily a problem if you don't need it.
Con Synchronization requires use of Trilium's sync server
This can be problematic to set up unless you have a web server that will support the requirements of this.
Con Built into VSCode
If you're not familiar with VSCode, there may be a steep learning curve.
