Horizontal space on the toolbar is precious and scarce, and that {nav Reload} button is taking up some of it, which makes it more difficult then necessary to add items that would be more useful.
Once there's a {nav Reload} button in the context menu, it can probably be safely removed from the toolbar. It's not useful for local views since KDirWatcher updates the view automatically. It //can// be useful for network views, but those are a minority of use cases, and with D12215, it'll be accessible from the context menu.
Depends on D12215
