Some QOL change that are needed, when we are at the docks there should be a refill all button, and an toggle that let's us automatically refill all if we have the resources.
Maybe an host after mission farming timer we can set. So we make sure we get any farming and refinement done.
Being able to go tactical without disrupting other activities, especially gunning or piloting. I know the cephalon already talks when a crewships is near, but setting objectives as a pilot or gunner would be great as well. Single person talk commands are fine, but there also be a general notification system; maybe have the tacticians' tenno speak so they aren't drowned out like the cephalon. Not everyone uses mics, and typing takes too long(especially if you are piloting a slow or squishy jack)
I know this is only due to a technical limitation at the moment, but clientside picking the next destination and making it hard to troll by adding a voting system if it's initiated by players who aren't the host. With that being said maybe a way for players who really have to go to leave without consequences, like a call or orbiter button.
Locking/unlocking certain ship skill uses, I say this as someone who often plays as a crew member, I'm pretty lax with my resources as captain, but I would rather have the captain lock out an ability or resource than have to deal with them complaining about us using theirs.
As other people have mentioned some of the artificial limits that feel fairly grating. While I don't think we need that many modules; limiting it to 30, is fairly annoying, I had a bunch of MK1/2 things I didn't yet sell off, and lost some potential mk3s. I don't mind having to manage this but this should be laid out better, with an easy way to mark things as junk or sell in bulk.
