I posted my top 10 suggestions on the official forum, but it was deleted because some people started trolling (I guess this should be changed too...delete flaming posts, not the entire thread). Since Bioware is listening to player feedback and have made several QoL changes in recent patches, there's always hope they'll do more. Add your suggestions.
1. Add a quick travel option for your ship. Could be similar to the fleet pass. I despise having to go though 3-4 load screens just to get to my ship.
2. Add a target of target frame. If you ever PVP or raid as a healer/tank in this game, you'd know how frustrating it is not to see what your enemy is targetting. And no, assist is not the same as ToT.
3. Allow ctrl/shift/alt to be used as modifiers for abilities casted on the focus target.
4. Add key bindings for summoning/dismissing companions. Also, let us move companion abilities to the companion bar. I'd prefer not to see attack/passive on its bar. And no, I can't afford to expand the pet bar on a main bar, since at level 50, some classes have combat abilities that cover all 4 bars. Sadly, you can't bind abilities in this game without putting them on an action bar, otherwise that would solve this issue.
5. Targetting nearest target needs improvement. The cycle range is too long. It often targets enemies that are out of your spell's range when you tab target. This is extremely frustrating as a tank when you're tanking giant enemies against a wall and can't pan your camera to see what you're targetting.
6. Show Usable filter on vendors/AH needs to be improved. In most cases, it shows the same list as Show All. I'd like not to have to go through a list of 30 non-heavy armor and weapons I can't equip, just to see the items I can use.
7. Allow searching on the AH just by name.
8. Every time I level, my relics are removed from my action bars. Not an issue at 50, but very annoying if you level while in combat.
9. Allow hiding legacy name selection window. It's silly how it pops up every time you get a load screen. I'd like to be able to make a selection at a later time when I had more time to think about the other characters I'd be playing on that server.
10. Add an option to not let my map go transparent when moving. Very minor, but often times it's very hard to see quest objectives and impossible to switch zones on the map when moving.
