I have a sequence made up of several sub/nested sequences:

The timecode of the main sequence starts at 00:00:00:00. When I get feedback from a client saying "remove the shot at 00:07:11:03", I go to that timecode in my main sequence and open the nested sequence. The nested sequence has its own timecode, by default starting at 00:00:00:00, so finding "the shot at 00:07:11:03" becomes meaningless, because that sequence actually starts (in the master sequence) at 00:06:47:05. So, to make things tally up, I change the "start time" of my nested sequence to the same 00:06:47:05, which makes everything super duper.
It would be nice if, in the "Start Time..." dialog box, if there was an option to "Inherit Parent Sequence's Timecode" to set the start time to whatever it is in the master sequence. Not sure if this start time should then auto-update if I then change the position of that sequence in the master sequence or not...I haven't thought it through that far yet!
