I noticed that the homepage and Explore pages and profile pages all consistently use the #number URL fragment when scrolling synths but now also append the collection ID of the synth after a comma.
Unfortunately the CID does not affect anything - only the number.
We also see the updated debug panel that we saw previously in Henri's recent Chrome extension moved into service on the main view page of the Technical Preview site with refinements such as:
:: reset debug panel settings to defaults
:: the 'slideshow' setting (can't recall whether this was there before or not)
:: the entire Path set of variables including...
:: smoothSpeed (meaning, I think, that the viewer will compensate for uneven spacing of photos through a scene and base its movement on the space of the scene, instead of basing movement on where camera positions exist and giving each image a particular amount of time)
Let me know what I've not mentioned. I still don't see a new Search page yet.
