I am pretty sure we discussed this a while ago, but we had a storage problem. May be worth looking at now since a lot has changed and from what I could find it may be possible now? @alexsparkes @davidcralph

Wessel is correct - there's a very small amount of storage that can be worked with via localStorage (5-10mb I believe). We're investigating alternative options such as Dexie that could be used to fix a lot of the storage issues with Mue, but it's a very large task so we don't know when it will be done.

Another problem would be the wallpaper would have to be downloaded whilst the user has the tab open. We would need to rely on the user not immediately jumping to another tab and/or having enough internet speed to download the second image after the first one loads. It looks like @eartharoid implemented a feature that gets the next API request in advance, which speeds it up a little?

I think as long as we have a blurred hash image or similar immediately so there's never a black screen, that would be the best solution for now.
