(UX) Back button in headerbar?
When evince isn't opened with the intent of opening a file at first (so when Evince is manually launched and it shows the list of documents), there should be a way to quickly return to the list of recent documents, for example if many are needed or if the wrong document is chosen, without having to restart Evince each time. The simplest idea would be a "back button" in the HeaderBar, possibly shown only when Evince was not opened with the intent of displaying a specific file (so in "viewer mode").
