+Zecke's Implementation Thoughts
+
+
+Task: Kill the Dolphin Singleton
+Reasoning: Have more than one Dolphin TLW
+Approach:
+ 1. Create DolphinApplication to hold all TLW's.
+ 2. Make dolphin.h dolphomainwindow.h
+ 3. Change the Views to have a DolphinMainWindow
+ parameter
+
+Reasoning:
+ I find it more natural that the DolphinApplication
+ holds and controls the list of managed MainWindows and
+ will control the life time of them, specially deleting
+ them on exit.
+ The downside is that DolphinApplication and DolphinMainWindow
+ need to work together but this is managable
+
+ Making DolphinView::mainWindow() public. Most users of the
+ current Dolphin::mainView have a pointer to the current view
+ already. We could pass a second pointer for the mainwindow each
+ time but the same can be achieved by using the appropriate
+ DolphinView::mainWindow.
+ Another approach would be to ask the DolphinView to execute
+ actions on the MainWindow like it is done with declareViewActive
+ in DolphinView. I'm not entirely sure which one wins but currently
+ using mainWindow() does not show any negative impact.
+
+ 2 times Dolphin::mainWin was used to check if the view is current.
+ this can be made a method of of the view
+
+ 1 time we want the viewChanged signal of our mainwindow to update,
+ the UrlNavigator could connect a signal to a signal to allow this
+
+ 12 times this was used to access the actionCollection
