I was curious if there is a technical programming reason tridents cant follow across sectors like furies do?

Well, yes.. it doesn't work yet.

Furies are simple fighter-ships, Tridents are kinda wacky moving-stations that have a lot more inventory management and other cases that have to be considered.

It isn't an arbitrary limitation, it's a technical issue.. at the time when we added remote-commands for Tridents, like "follow", we added things that I knew we could finish and release in the short time-window available. We intended to come back and flesh it out (and still do), and make them more cohesive in following across sector boundaries and the like, but it'll take a little larger window of dev-time than what was available then.

Fair enough, I figured it was something like that. Thanks.
