I’ve hosted more themes as well, with links on wdlxtv.com

wdlxtv.com I’ve also done  a full write up on how to theme, however, it’s largely out of date and mainly for older devices

but the good news theming the hub and smp are significantly easier

just unzip,

edit the xml’s or replace images

zip and done
