Just to add to the OP of this point, clearly going back to 'modify' needs to have all of the fields populated as previously, but trying to enter an airfield code just appears to remember the last typed code, not necessarily specific to that field. So, having searched originally for AGP - SFO, when I go back to put a starting point in the origin field it suggests SFO:




There is also a problem in the routing codes field. If I have already put in, say, JFK and then want to add LHR before JFK, I put the cursor in front of the 'J' but as soon as I type 'L', the cursor jumps to the end of the string - so you end up with LJFKHR.





Otherwise, thanks for the efforts to keep it going and improve it too.
