Focused on the convenience of working in lists from the keyboard. The mouse is also fully supported (Drag and Drop etc)

Keyboard shortcuts:

Tests only in image based on OpenPLi or last BPanther(neutrino) images with GM 990 Spark Reloaded receiver in my preferred linux distro (Last Linux Mint 18.* - MATE 64-bit)!

Terrestrial and cable channels at the moment are not supported!
