How to manage mutiple Websites using the Visual Studo Code plugin?

For FTP and other purposes I am using Pinegrow’s Visual Studio Code plugin.

All my websites are mirrored on my desktop. Each mirror is a subdirectory of one main directory that has the path ~/Websites/Mirrors . Visual Studio Code’s sftp extension is to be used to synchronize the mirrors with the servers. The mirrored websites are on different hosting services.

I have seen this article about workspaces and global settings for Visual Studo Code:

The question is raised whether it is best for each mirror to have its own workspace, or should all websites be managed in one workspace and use contexts for each mirror in one sftp.json file?

My OS is Ubuntu 18.04.
