(1) Each addon has to work with plugin KodiLite version 1 only. If any addon needs some extra scripts or changes to any files in KodiLite - they have to be put in with the addon. That is why i had some addons in /lib. So - please check and put in /lib if necessary.
(2) You and I - and other coders - will need to know in future what was modified in the Kodi addon to make it work. So please put near the top of default.py - comment lines listing the files you have changed.
Also in the changed file - give some indication where the changes are - like
############fix start ########
############fix end#########
This will make it easier for someone else to modify addons in future.
I'm looking for some scripts but can't find them on google. I also looked on pc kodi to find them by following info from #79 the folders that you mentioned I couldn't find in pc for scripts.
Inside the default.py file what do I put near top line 1.
