Can I suggest that we have a seconds option for the Minutes to hide a timeout flight.
I think having at the default value of 30 (? forgotten what it was) may be increasing the chance of a problem - When I changed mine (purely on local traffic to 1 minute - the number of aircraft listed went from 67 to 25 - and all of those (bar 2 were moving) previously I had around 40 timeouts waiting to disappear!.
When the Quick Filter has been used (e.g. to select Flying over = England, there does not appear to be a way to clear the first box (flying over - or whatever is selected). Can this be changed please as I am not sue if clearing the word England from the filter actually puts it back to monitor all traffic.
Also, just a minor point - Location for EGTH (Old Warden) is I believe in the wrong position !
