Point 1 - what a pity! On Windows we can use Everything which uses the NTFS index to do really fast searches; it is a pity there isn't the same function on Mac OS filesystem (as far as I know). Note that point 2 is the same problem on any OS - if you open a file dialog, you have to supply the working directory for the dialog so it affects Mac OS, Windows, Linux etc. It isn't a problem that Apple should take care of - who says the dialog box should always go back to the same directory? In some cases it might not be required, which is why they leave it up to the application devs. Tell your app devs to stop being so lazy. For point 5, it is debatable. On Windows if you have multiple non-modal (or even modal) dialogs open as children of an application, Windows can sometimes get the Z order wrong and there is no way to alt-tab to that window, as alt-tabbing shows the parent window. So having a window switch option would be great (actually Windows 10 fixes this a bit with its Windows-tab overview system).
