Maybe some day an Android update will come out that lets you have any download prompt allow you to set where to save it and rename the file to instead of auto downloading for all apps. It is annoying the way it presently is.

That and allowing URLs to be opened with an App. I am terrified of hitting always and be stuck dealing with a app I hate.

Just keep hitting, this time only.

Or when an app does tell you but it does it in one of those small tool tips that are only on screen for like half a second.
