(this is a clone of https://github.com/sysapps/sysapps/issues/41. Please see that bug for discussion and proposals)

Various vendors have expressed an interest in having a splash screen for when an app boots up.

Previous attempt at standardising such a thing:

https://dvcs.w3.org/hg/nativeapps/raw-file/tip/splashscreen/Overview.html

It might be good to reopen the discussion on sysapps.

Use case: Because of the limited processing capabilities of some devices and the amount of time it takes to initialize a Web runtime, there can be a small - yet noticeably perceivable - delay between when the end-user starts an application and the application actually becoming available and interactive to the end-user.

Depending on the complexity of the application and the processing power of the device, this delay can range from a few milliseconds to a couple of seconds. When applications take more than a few seconds to load, it can be disorienting to end-users as nothing is displayed on the screen; leading to a poor user experience. Native applications overcome this issue by allowing developers to use a media file that is displayed the instant the application is launched. Such a file is commonly referred to as a "splash screen" or "launch image".

I think it would be good to add the splash property as supported on BB's configuration.

---- Proposed text ----

3.x splash member

The splash member is an object that represents the image to display on the screen while the application loads. Paths beginning with "/" are treated as relative to the origin of the app.

@hollobit thanks for the proposed text. We have not received a lot of demand for this feature from other potential implementers, so it's going to be labelled LATER (thought not sure if we will just put into a LATER milestone or close the bug).
