Which add-ons do I use?

Hi,

I have been using KODI 14.2 for a long time, and have done quite a few customizations over the period. I am thinking of moving to a newer version, and want to back-up my video library first as described here: HOW-TO:Backup_the_video_library (wiki)

However, it is stated that add-ons and their settings are not backed-up. Will installing a newer version of KODI add my existing add ons, or will this need to be done manually afterwards? I simply no longer remember which add-ons I am using (I know there are some related to remote controls, short cut key strokes etc). Is there any way of finding out which add-ons are in use, so I can take note of this before I install a newer version. Otherwise I am afraid I’ll use weeks and months of reinventing the wheel before I can get a new KODI to work like I want?

To all who have upgraded/updated before, my apologies for these very basic questions, but I have never tried this before, and I am very nervous that a system I have used and relied on for many years, and where I have spend 100s of hours tweaking it to my liking, might not work properly…. Blush
