Hi All,
LibreELEC noob here (Krypton v7.90.005 ALPHA, Aeon Nox 5 SiLVO skin), 3 year XBMC/Kodi user (on Windows). All is working well, no complaints!
I was trying to find a way to change font sizes in my LibreELEC installation (easy in Windows, mildly obscure in LibreELEC) and googling revealed I would need to SSH into my HTPC and use something like Putty to open and edit the appropriate font.xml file. I just wanted say I found another way (probably all wrong and my HTPC will soon burst into flames).
I ran the system backup from the LibreELEC administration program, copied the resulting .tar file over to my PC, extracted it with 7zip, found the font.xml, edited it with Notepad++, re-tarred the archive, copied back to the HTPC and restored. It seems to have worked! So far, anyway...
