Just had a look at it. It's ok but there are some serious limitations in comparison to Obsidian which would make it unsatisfactory for me:
- No command palette
- No block inclusion
- Notes appear to be stored in databases rather than just as markdown notes on the file system. Backup of markdown notes seems to create a flat group of folders with randomly generated file names.
The only thing that is making me not switch to Mem is lack of tables. I really heavily on tables for notes. And that has not yet been implemented in Mem.
