Feature request: Hint at how files can be managed

[sonicer105]

I noticed that the file management interface for servers does not intuitively communicate that you can right click to manage files. This was something I only figured out by reading the documentation.

I had two possible suggestions on how to address this:

1. add a hint telling the user you can right click in that panel

2. add a vertical dot menu to each item that will invoke the right click menu when clicked (similar to how Nextcloud, Google Drive or OneDrive handle it)

Thanks for your time!
