Files: Add new "Projects" entry to sidebar
This may be something to discuss with the xdg-user-dirs people as well, but, developers often use some sort of 'Project' or 'Development' folder in their home folder to store code. Having this folder automatically added to the sidebar with the other XDG directories can be incredibly efficient for developers.
Ideally, this folder would be treated like an XDG folder (and maybe added to xdg-user-dirs), with an icon and sidebar entry.
macOS provides this feature for the ~/Developer
folder, as seen at https://mastodon.social/@_german/109825906749279945
