title: How to make tkinter Window floating in i3 windowmanager
body: <p>I'm just playing around with tkinter in python a little, but have some "troubles" with my i3 (tiling) windowmanager.</p>
  
  <p>I want to create a floating window for entering a value (similar to a "Open File" Dialog). This has to be possible, since Gimp for example works with floating windows in i3, too. Of course I'm not sure if it's possible with tkinter.</p>
  
  <p>Does someone happen to know the problem and found the solution? I guess there's got to be some sort of flag to set on the tkinter.Tk() widget.</p>
