asari dancers in the tempest

a way to go to the tempest when exploring on foot

some sort of fast travel to the nomad when on foot
running on walls, we alerady have the jetpack

more than three powers active

There are some forward stations where you could do that.

As others have said, the ability to go into the Tempest without leaving the planet would be nice. Especially when I just want to chat.

I find some of the character movement give me a bit of a headache. I feel like some of the little rocks and things on the ground are too easy to get stuck on. They should just let you more or less walk through things that are not more than 1/4 of the way up to your knee. I seem to remember this being a bit annoying to me in DAI, but it seems even worse in MEA. Related to this is that the camera view seems to lurcha around way more than it did in other games. This may be just me having this problem since I am bit prone to migraines. I usually leave my weapon drawn becasue the wider FOV makes my head hurt because of the way the camera works.

Let me take out the augments without having to go through so many steps and station switches.

I want to go back to the old health system, or at least something closer to it. Use the current system to fill my health dispenser, not to heal me. Same as the ammo system.

I want to be able to sit down on chairs and couches. A completely useless feature, but I want it--maybe because I have played too much Star Trek Online.

Another thing about movement: There is a movement delay that seems to happen right after a conversation and perhaps other times. It bugs me. Granted, it is more realistic this way, but I just want to get moving.

LARGER FONT - being saying this everywhere I can with the hope that someone from Bioware will see this (no pun intended - ) and get it fixed. Can't read most of the text without seriously squinting or standing up and moving two feet from the TV.
I read somewhere that font size MAY be considered at some point for patching. Please patch Gods ...consider it now.

I don't think I've seen anyone mention the lack of a customizable HUD. The Nomad HUD is an eyesore. I don't need permanent instructions plastered on the screen regarding Mining; Acceleration; Jump Jets and so on... If I need more than one advisory regarding this, then my stupid ass should pause the game and look up the controller layout. For a game built around beautiful environments, so much clutter onscreen makes little sense.

A mute button for sam. I really just want to shut him up. If he won't solve the remnant puzzles for me which are a PITA for me, and if he won't be accurate about when I do and do not have mail, then he just needs a mute button. Now I know how joker felt in ME2. But no, I am not going to date SAM if he shows up in some virtual body, which he probably freaking will. Also, when that happens, I'm going to say 'called it' in every subsequent thread where people are flipped out about it, because you know they will be.

Also, check mail somehow from my omnitool. Or forward station. Seriously, I don't want to have to go back to the tempest to check mail. I want a screen I can look at anywhere just to see them. Vid calls too while we are at it because Shepard could look at hackett on his/her missions in ME3 and I think it could be done before then. So why can't I use my omnitool for that too? Anything that saves me those damn loadscreens. There should be a moratorium on anything that adds more loadscreens. 

They also need to expand the radius for initiating conversations, at least on PS4, as well as for opening some containers. Often I have to get ridiculously close or jump around for awhile before I get the triangle prompt, and it's especially annoying for those conversations because our faces are practically touching.

"Claim all strike team rewards"-button. Now I need to claim each reward pack individiually and I have around 90 rewards pending

May have been said already, but a map HUD with a built-in waypoint.

Add more active powers to the wheel.

A better and easier way to equip after gear/weapon creation, including mods.

The ability to turn off SAM:The Weather Man.

Add invulnerability during mission dialogue.

etc..

If i had to pick one, in addition to the very good ideas mentioned already, it would be to wear any armor. Why be restricted to one "good" armor set if you are a biotic, or tech, or sniper? Make 6 sets of cosmetic armor and let us mod them for bonuses.

It would be cool, if there could be a way to get SAM out of your head. Maybee with a brain surgery. I really don´t like the idea having a AI in your head.
