It would be great to have the corresponding frame number (based off of the chosen start frame from the selection below) to the left of the selected file. Many times I have 10 frames using the same file, then a different for a couple of times, and so on. It can take up a bit of time to double check over things to be sure the appropriate amounts are set.
On a side note, if you accidentally select to open a image rather than clicking the film strip, it will clear out the list. It would be great to see a solution around this.
