[Feature] Single click on directory should open windows explorer

[Hofknecht]

suggested by Stefan M.:

There are two ways to open to the directory "P q20":
-Double click on "P q20"
-Single click on A.

New:
Single click on "P q20" should open windows explorer (instead double click).
(Single click opens the submenu direct, but that happens after 100 ms anyway)

Probably single click as new default and double click over options
