Comment 8 for bug 1821094

I'll take a stab at this. My plan is to:

* add another option to itemSvc.fetch to skip the unshifting, so that these calls can be done concurrently (aka speed up the refresh)
* let the user know if the refresh is taking a while, probably with a toast message in the bottom right corner
* wait on the "Item(s) saved" toast until after the refresh, to cut down on some of that confusion

...and see how much that helps.
