Hello Richard,
I would find it quite handy to view a layer(s) timecode in the cuelist window next to the cue itself.
If there was a timecode window i could drop into the cuelist in the same way as other devices and set which layer/cuelist/device it pointed at, then I think this would be quite useful.
In the case of layers if it could also act as a counter between the inframe and the outframe with the option to count up or down this could also be very useful.
