Regarding check's for used sends, they are not used because multiple tracks or buses can use the same send.
Yes, but only one Send can be selected in the drop-down menu for that particular track or bus and the particular Send number.
Examples:
Track 1, Send #1-Delay bus @ 0dB <--check mark to show active in list.
Track 1, Send #2-Reverb bus @ -3dB <--check mark to show active in this list which is separate from the other.
So in other words, the check mark I am referring to would be within the Send "selection" menu. Only one Send is possible per Send number.
