** Description changed:
- When a Preview needs to fetch online data, it can take a moment before being
displayed.
+ When a Preview needs to fetch online data, it can take a moment before being
displayed.
After a click on a result, there is no visual feedback on what is happening
and no way to know if the click has been acknoweldged by the Dash.
This could be fixed in different ways:
- Showing a spinner on the result icon.
- Showing a spinner on the cursor.
- Instantly opening the preview pane, with, as a transition : the
result icon on the left pane, the result title on the right, a spinner
on top (the same as the one appearing when navigating between previews)
and updating the content when the actual preview data is here.
+
+ -----------------------------------
+ Desired solution:
+
+ 1. Reduce the incidence of this happening by speculatively pre-cacheing
+ the preview data. This pre-cacheing should start as soon as the results
+ finish loading into the screen, and should continue until the user exits
+ the Dash, performs another search, or opens a preview. When the user
+ opens a preview, results subsequent to the preview should start pre-
+ cacheing.
+
+ 2. When the user opens a preview that is not pre-chached, the preview
+ should open instantly, and the content should then load into the already
+ opened preview. A spinner can be displayed in the place of the image to
+ inform the user that the preview is loading.
+
+ Note the pre-caching is very important to reduce the incidence of the
+ user seeing the loading state. All major browsers currently
+ speculatively pre-cache content, so if we are match user's expectations
+ regarding speed of content display (shaped by using web browsers) this
+ is something we really need to do.
