A couple of really nice bits of optimisations:
this gets rid of the imagesLoaded library, which was overkill and now we use a native system to do the same thing:
and this gets rid of the unintentional jank that was the clashing and unneeded core highlighting animation on first tile of new set when scrolling which made it look like it took time for the true background colour to load (but was just a CSS thing):

Sponsors (>= $7/month) should now have access to the sidecar once again.
If you are already set up with discourse-locations-early-access this way, use the same technique to clone sidecar - any issues PM me!
If you are a new sponsor and want to know how to get access to the sidecar PM me!
NB the Theme Component will remain public.
Are this component and https://github.com/merefield/discourse-topic-list-previews-theme.git same and/or latter is discontonued url?
GitHub - merefield/discourse-tc-topic-list-previews: Enriches the content and layout of topic lists · GitHub remains public and I’ve no plans to change that - that is the correct url and has not changed.
I guess at some point the repository was renamed. But this shouldn’t matter as long as merefield doesn’t create a new repository using the old name.
Yeah, the theme component switched org at one point (from Pavilion).
The original plugin became the sidecar and in that process the front end was removed and moved to the theme component.
Essentially this is now a freemium setup - those who don’t need the sidecar features continue as normal.
Clear as mud? 
Update, to avoid broken builds I’ve restored a public version of the sidecar to the original url:
https://github.com/merefield/discourse-topic-previews-sidecar
but note this is now unsupported and should be removed asap.
There is a new admin notice.
For GitHub sponsors contributing >= $7/month please contact me privately if you’d like access to the supported version.
