As a relative newcomer to Kodi, I suspect it is capable of all sorts of things I’m not even aware of. I’d like people to use this thread to mention any Kodi add-ons or extensions that they particularly like or find especially useful. Maybe everyone can get some fresh ideas!
EDIT: please don’t just mention the names of the add-ons you use - explain what they do and why you like them as well. 
As someone that uses only uses the vero to play media I feed to it with usb and only uses Twitch, YouTube and subtitle addons i feel as if I’m not even scratching veros potencial.
I’d love to love to know what can be done
Tell us about Twitch.
I probably use iPlayer and PSVue the most.
PSVue you obviously need a subscription for.
Twitch.tv is the biggest game streaming platform on the internet
The add on allows you to sign up with your own token and basically navigate as you would on the website. The only thing is that the addon is a bit hard to navigate if you use the remote.
Plays 1080p@60fps fine if that’s the streamer is offering.
Don’t know if chat is supported would have to connect with a keyboard to find out
CinemaVision is the best add-on, but unfortunately the Vero 4K / OSMC doesn’t play nice with it at the moment.
I’m glad you like it but It does sound kind of gimmicky after all who wants to willingly watch movie trailers ? Its the worst part of going to the public cinema for me. You get all those spoilers you didn’t ask for.
It’s for more than just trailers. Before the main feature it plays movie trivia slides as I’m making the popcorn, plays bumpers, personal home theater intros and dims/turns off the theater’s Hue lighting. If I have to pause the movie for any reason it automatically turns the light on and shuts them off when I resume.
I might sound boring but I like the picture slideshow addon so that when my device is idle it triggers a screensaver of all my movie artwork
Well on my vero4k, i’ve got Viaplay(scandinavian “netflix”), Netflix, Youtube, Spotify, Transmission client, rTorrent client and my own Xwindows-chromium OSMC addon.
In additin to running Kodi, it runs Nextcloud, Pihole(with modifications to run on OSMC), rtorrent, tranmission, irssi, VNC server. Still have 1GB ram available.
My OSMC 
The idea is not just to list the add-ons you use, but also to describe what they do and why you like them.
(Original post edited to reflect this!)
trakt.tv since its tracking my media consumption for ages and saved my watch and history more than one time due to a fucked up db and or upgrade!
In addition to some of the ones already mentioned, I rely a lot on Unpause Jumpback. It rewinds whatever you were watching back by xx seconds, after it has been paused for yy seconds. Invaluable when my friend has to go to the bathroom in the middle of a movie and takes 2 minutes to do so, and then we all have to be reminded of what just happened previously.
Backup - haven’t tried built in in a long time, started using due to some additional options
Pandoki - for my Pandora premium subscription
Ted - great for my kids and I
Recalbox launcher - for jumping into my dual boot for retro fun
And OSMC skin for fantastic customizable screens
In no particular order:-
I’ll start with what is pretty much a niche addon which is ESPN Player (subscription required and not to be confused with the main ESPN addon),
this is a great for fans of American college sports who live outside the USA, although in my case I’m only a fan of college football so this is soon to be retired for me until next September, but it offers bitrates far in excess of what’s available on the ESPN Player website giving a great broadcast quality HD viewing experience.
Next I use the Apple iTunes Podcast addon a lot to listen to my favourite podcasts without the need of having an Apple ID or account.
The YouTube addon also gets used a lot in my humble abode but not in the way most people would use it, its sole use here is for watching trailers for the many movies in my local library.
Back on the sporting front I also use the Eurosport Player addon which is much better than viewing through the website or the Fire TV app as it gives streams in 720P at 50 fps rather than the 25 fps on offer the last time I used the other methods.
Last but definitely not least is IplayerWWW which must be my most used addon, I far prefer using this addon for watching or listening to BBC content than the homogenised way Iplayer content is served up on every other device known to mankind lol.
I used to use the NFL Gamepass addon a lot but sadly it hasn’t been updated for a while and now fails to work so I’m forced to use the Fire TV app which is a goodish substitute.
I just installed pause jumpback on my vero 4k+ and it works as intended but it seems that when the audio cuts out for 10-15 sec when I press play again which basically makes the addon irrelevant. Does this happen to other people too?
@sam_nazarko same thing that happens if you rewind instead of skip forward and backward with the forward and backward keys on the vero remote during playback.
Tested with but happens with other media too.

Meh maybe I should open a new thread
FF/RW is quite broken in Kodi
Do you think this will get any improvements in v18 ?
No – I don’t think so
