When working with the timeline view opened I find it quite distracting as every time the file changes the view has all text removed and then fills in for the new file. One idea to prevent this is to disable the items in the view but leave them there until the new items are ready (or until some short timeout has elapsed), that way it would change from a full view to another full view.

@Tyriar I think I have improved things a bit in master. Can you check it out in tomorrow's insiders? To me it feels the same as the Outline view.

@eamodio it still flashes empty and then full though?

When flipping between 2 files multiple times, one appears to be cached and the other not?

@eamodio what was the fix that happened here?

After discussion in Friday's standup, we will now not update the view until we've loaded the fastest provider for the new file, and if the user interacts (clicks on, etc) any of the items in the view while we are still loading, then the view will switch to the "loading" state.
