Sometimes Dolphin lose synchronization with the file system. For instance, if I change the file name or add new file from some other ways, such as from a terminal, Dolphin will not refresh its content for a rather long time, even after I've re-opened the folder. So I think a manually controlled refresh function might be useful.

Isn't that covered by the View->Reload menu entry (bound to F5 by default)?
You can either - press F5 - open the "View" menu then click "Reload" - Right-click the toolbar, click "Configure Toolbars" then drag the Reload action from the "Available actions" to the "Current actions view" Closing as NOTABUG.
