Is it possible to add a visible marker to the cue points? For now I used the loop points 9-16 to get a visual representation of the cue point. So when I add a cue point the patch will take the cue_point_fraction as the loop_endpoint of "loop 9" and set the loop_startpoint to "loop_endpoint -0.002". I think the picture below should clear things up. Now if that could be implemented into the "uiwaveform"-object with a different overlay color than the loop's grayish overlay, that would be so cool.

What you see is the cue point not a loop point. The white indicator is the starting point.
Oh, just a quick side note: Why is it that the "uiwaveform"-object has a limit of 16 cue points and 16 loop points? I am not much interested in more than 8 per clip, it's something I'm just curious about.
