One has to be a rocket scientist to be able to configure this thing!
I found on KODI forum that to make fonts biggrer you have to edit this file (after logging via SSH, how user friendly):
/usr/share/kodi/addons/skin.estuary/xml/Font.xml
BUT! You cannot save the changed file, it says FILE SYSTEM is READ ONLY.
So how in the world can I make fonts bigger and readable from my sofa?!
On the other hand, I need to modify this file:
userdata/keymap.xml
To make remote control's back button work as intended.
No idea where that folder of file is.
Please help 
My Slimdevices Transporter died 
The worst day ever.
This RPI4 thing... Jesus Christ, do you think non developers would ever be able to configure it?!
