title: Pyinstaller adding splash screen or visual feedback during file extraction
body: <p>I create a single file python application with Pyinstaller using --onefile parameters.
  Everything work as expected but the startup time is around 10 seconds on my machine. The problems is that during the file unpacking process of Pyinstaller package there are no visual feedback, so you don't know if the application is starting or even if you really clicked the icon. This problem became worse if the machine is slow (on my test with a very old machine i need almost 20 seconds to see the first login of my application)
  There is a way to create some splash screen or visual feedback (like a progress bar as on unpackers) during the Pyinstaller bootstrap sequence?</p>
  
  <p><strong>Please note</strong> the question is about Pyinstaller unpacking process <strong>BEFORE</strong> the real application will be executed not by the application itself that already has is own splash screen</p>
  
  <p>thank you</p>

  My application is FULL GUI so i prefer to not use the console as "visual feedback" during the unpacking process.</p>
