I've never found useful the "time from red marker" and "time from green marker" on the display. Maybe it is just a personal preference;
I recognize they give a cooler hacker/nasa look
but never used that info for programming.
There's also a detail I miss from the old V6: it used to be a little bit more evident when a scene was playing VS when a scene was interrupted, especially with the X tool, compared to present versions.
See:
It is evident that nothing is playing in the first red area, while it feels something is still playing in the second one.
However it is probably already solved or taken into consideration by:
in the next version of the software, the fade in/out options will be additional blocks before/behind the scene block.
And again probably just a matter of personal preferences.
