In fact, there are already existing markdown/vscode plugins, but I still have to say that it is not easy to use. . .

In addition, I don’t think that Joplin can fully accept Evernote users. It is just a personal open source project, and what open source projects like to do is use the coolest technology to make the worst product, few people are willing to free Deal with various details and edge issues. According to experience, if it is found to be profitable, commercial companies will come to make products and do better (Eclipse => Jetbrains IDE or Vim/Emacs/Subline/Ohter... => VSCode).
Like here
- OneDrive errors in Joplin "The maximum request length supported is 4MB" and "FetchError"
- Feature Request: 21vianet onedrive Synchronisation
- OneDrive Sync Question
The reason I am still here and developing some plug-ins for it is that there is really no other very good option, so I can only choose it.
