I don't know if others find this frustrating, but I would much prefer that when you click a column heading, the list should be sorted in ASCENDING order first, rather than the descending order that it does now.
More suggestions for keyboard shortcuts:
M - go to MyFlights
N - go to Network flights
S - go to Smartview
C - go to ACARS
A - go to Alerts
F - Advanced Filter
Ctrl-F - turn on current Filter
Ctrl-B - show ADS-B flights only
Ctrl-A - show All flights (turn off filter)
Ctrl-S - Sort by current column
By the way, I know that F9, F10 and F11 already do what I propose M, N, and S to do, but F9 doesn't work for me, and using the keyboard gives us the full selection of tabs, and are probably easier to remember.
