[IDEA] Integrated file manager function

[McLaine]

I would like the option to rename files and rearrange them

But... whatever you're connecting to the Pi from is on the network and has a file manager application yes? Why would you need to install one on the Pi?

the idea is exactly not to install a file manager application on the PI, but to use the application which I have already opened.

Just to ilustrate the use case:

I realize that I have  a folder "Santana" and a folder "Carlos Santana". In order not to switch the application it would be nice if I could cure this by duing it within the application I've already opened (Moode UI).
