better filemanager on HD2 FW??

[Bean]

Hey,
I'm using a long time, the HD2 firmware on the HDP-R1. Thanks for the excellent work Olegin & team!
Is it possible to integrate a good filmanager? e.g. midnight commander over telnet or TV (better). The filemanager of HDP-R1 was better, you could select multiple files and copy files from the network to the internal HDD ...
Thank you
