I tend to think of this as a bug, but … maybe it is an RFE. And so, here I request it.
Recently, I needed to restore two documents from Backup. I went to Joplin's "Help" > "Website and Documentation" only to discover that … there's nothing there about Backup and Restore.
Eventually, I ended up on the Plugin site and then the Backup github page, but …
Backup is installed by default. Freehand Drawing is now built-in (why isn't Backup "built-in"? they are both plugins, right?). I think perhaps once a feature becomes this prominent, they have to be represented in some form or fashion in the Help section of the website. Now, if you search for Backup on the website's search tool, you get a lot of hits that are not Backup and Restore. If you do the same for Freehand Drawing, you get a series of blog posts.
What is needed is some page for each that then leads to more information. Or flesh it all out in that page if you like, but I think you get what I mean. They are prominent features now. The need to be given higher status, I think in the Help docs.
Joplin rocks!
