I agree with the modified Fleet Emblem creator to make our own assignment patches for Enterprise era uniforms. I also think we should be able to get some form of similar tech for our TOS uniforms as those arrow-heads that eventually became the Starfleet insignia was actually a mission patch for the 23rd century Enterprise.
I would like to see more options offered for the ENT patches as well, it makes no sense to have them read "Enterprise" if the officer doesn't serve on the Enterprise. Either a generic one or a few other choices would be nice. If it just said "Starfleet" instead of "Enterprise" - that would work with any ship and crew.
