I've put in a request for this a long time ago, but I'd really like to see time marks of some sort on the overview window.
You've got a file open - how long is it? Dunno - have to scroll to the end to see.
How long is it approximately after I edit something out of the middle? Dunno - still have to scroll to the end.
Have tic marks every 30 seconds or something would at least give you an approximate idea of file length, or help you get close to a specific time with a single click, instead of scroll ... scroll ....
