In the mongo command line, timestamps are displayed as a tuple of two values corresponding to the two 32-bit fields in the timestamp object itself. However, in Compass it is displayed as a single long number (I'm assuming the value that corresponds interpreting the two 32 bit values as 1 64 bit long...)
I find the command line view much more usable. So much so that I currently cannot use Compass to help me troubleshoot a bug in our application.
Please consider displaying these in a more consumable format.
For reference, I've attached a screenshots comparing how the two represent identical documents
