I've worked with Prego in the past and really liked the preview feature that you can see what channels are comming in the next cue when you had your channels set to "Active" (in Prego it was called "Packed").
Right now when preview enabled you cannot see channels that are comming in the next cue, when they were never active before. (And yes I know its supposed to be like that because its set to "Active")
But it would be really nice to add an option to include channels from the next cue in the "Live Summary Active (Tab 1)" Tab when using "Preview".
So as an example: I am in Cue 1. In Cue 2, channel 12 is going @ Full.
Currently you can only see upcomming channels if you have "In Show" or "Patched" etc. enabled. However often you dont care about seeing those channels (because it shows channels used in subs and stuff too) and only want to focus on channels that are currently active or upcomming.
Below I've attatched to images.
How it is in the current version of EOS (V3.3):
How it could be maybe in later versions, maybe different colors to show that its a channel who becomes active in the next cue, just to visually differentiate the tombstones:
Since "Preview" is a softkey only thing, it could be easy to extend it a bit, for example like:
{Preview} {Pending} {Show_A_B}
Thats it, I hope you didnt cry because of my english and got my point.
EOS is a great software and I really enjoy using it.
Thank you
