Utilize more mouse button actions in Directory Menu

In Directory Menu plugin's dropdown menu currently only the left mouse click is utilized for opening files. Directories are shown upon mouse hovering and cannot be opened in file explorer, except if the additional Open Folder menu entry is enabled. This is a feature request to utilize more mouse button actions in Directory Menu, for instance:

1. Double (left) click on a (sub)directory to open it in a file explorer (working regardless of whether Open Folder entry is enabled).
2. Middle click on a (sub)directory to open it in a terminal emulator (working regardless of whether Open in Terminal entry is enabled).
3. Right click on a file or a (sub)directory to show the right-click menu (as on the desktop).

This feature request also supersedes and extends the 12-year old #11 (closed) - see number 1 in the list above.

Additionally, number 1 and 2 could be implemented in the plugin icon as well to act on the top-level directory.

The middle-click on an ordinary file action is not listed above since I couldn't find a good use for it, just mentioning it as a food for thought.
