I like delta timing in leaderboard cause it replaces well the ghost. Ghost is a bit disturbing and delta timing give a more accurate information. But I'd like to see 2 improvements in leaderboard sessions: 1) Be able to set delta timing reference to the loaded ghost, for example with a key bound to this function. And the opposite function: reset delta timing reference. 2) Be able to restart session without loosing current delta timing reference. When I fail a lap in a leaderboard I use the "restart session" key, and so I loose it. Workaround is to "escape>back to garage>yes>drive" but it's longer and need mouse, and cause the session timeout is one hour, soon or later I'll loose the timing reference anyway by an automatic session restart.
