There is still a copy of the old wiki at the following location:https://github.com/robwebset/script.videoextras/wiki
But if people are interested I may be able to create another button in the VideoExtras settings to update the Estuary skin - what features are needed - just a button on the video Info screen? (The context menu option should still work on all skins). Do people use/need the overlay images for things that have extras?
P.S. Thank you for the donation
And I just realized I didn't answer your questions, at least not clearly; see below.
Q. "what features are needed - just a button on the video Info screen?"
A. That would be great, Rob, but I'm not seeing anything in the context menus for Estuary or Estruary MOD, either.
Q. "Do people use/need the overlay images for things that have extras?"
A. I do, and anecdotally (from the Kodi forums), I would say many others do, too.
I'm sure you are aware that many, many people use, rely on and appreciate VideoExtras. One of the single most useful addons I've found in Kodi (I started using XBMC with Gotham).
