Options/Configuration should show storage location

[yafp]

I am currently testing Joplin, one issue i had is that after creating some test notes & notebooks i can't really figure out where those notes are stored.

It would be helpful if the options UI would display the storage path.

Alternatively, if this project is not open to configuring the actual location of the synchronized files, it would at least be helpful to document WHERE notes are stored.

Yes I will add a line in the Option screen to show where the files are located.

On Windows: C:\Users\YOUR_NAME\.config\joplin-deskop

On macOS and Linux: ~/.config/joplin-desktop

For the terminal app, it's under the directory "joplin" instead of "joplin-deskop"

Given that #42 exists and seems to have more discussion on this same topic, could this be closed as a dupe?
