I'd like to choose at log-out how long my trident persists. 5 minute minimum, some reasonable maximum

If they implement this, they'll have to fix the correct case issue. Imagine the confusion if you set a persistence duration for 3 hours but you used a lower case 3 instead of upper case.

I've tested around a litte. The bug seems to have gone. I believe it may had to do with a few sectors behaving oddly around in Odia/Sedina. With the restart the devs did 1 or 2 days ago, it was probably fixed. Thank You! Case closed.

Perfect. More resources to fix the case inconsistency bug.

Savet, what if I actually want my ship to remain in-game for ³ hours?

+1 to csgno1's idea of configurable post-logout presence.
