How to look up in "decoded protocols"

Additional feedback about current master (please note my previous post):
This is how I look at one I2C request/command and data reply from slave.
I zoom out to a decent size for the job, but the blue data fields are unreadable even when there are plenty of room around.
When slinking anything in “decoded protocols” , the nice, smooth, animation does also mess with the final zoom level, after a “travel” , zoom level should be the same. - it is perfectly fine to zoom out during travel, as it gives a nice impression of what-is-where, but the end zoom should be preserved.

Also, there are green/red dot’s on I2C data line, the red is not always after a NACK, I failed to find any documentation on the meaning of those.
