title: How to remove fragment from the back stack?
body: <p>For example there is 3 <code>Fragments</code> in back stack. Smth like </p>
  
  <p>Fragment1, Fragment2, Fragment3.</p>
  
  <p>Fragment3 is the last added fragment to stack. Is it possible to remove Fragment2 only? </p>
  
  <p>I found out that it's possible to remove Fr1 and Fr2 together, or Fr2 and Fr3 together, but not fragment from the middle of stack.</p>
