In working with Pro Tools, we usually rely on receiving an error when you are monitoring how many tracks you have already used for the session. We can always count the tracks manually, but that does not work well when you are almost at the track count limits.
To alleviate this, I propose that there be a Track Count statistics window, where the following information can be seen:
"Current Track Count (Maximum Track Count @ Sample Rate)"
For example: "Audio Tracks: 94 (128 max. @ 44.1 kHz)", "MIDI Tracks: 48 (512 max.)", etc.
It may be added as a window, or included in the System Usage window, or anywhere that it can easily be accessed. This will help resolve some confusion with Pro Tools users who are not that familiar with the track count limitations.
