Following Journler — with Obsidian

Many years ago there was a brilliant piece of software called Journler for mac. In someways this software was like WordPress for local use, it connected with many of the Operating APIs (like for pictures). I thought it was amazing. It officially died in 2015. However, for note taking I recently found a tool called Obsidian. But the content of Obsidian is maintained in markdown. I wonder if it could take the same place as Journler. One interesting idea the use of graphing (network graphs) from notes and tables in those notes.
