A simple list really and in no particular order. Some of the little things in STO just tick me off the wrong way. Kinda like the way Scotty would be if a Tribble drank all his whisky. anyway, is my list so feel free to add your voice or flame away. :P
1.
Walk Is rather simple. Why rush everywhere. Sometimes I just want to walk.
2.
remove kits/shields/armour When beaming down to a mission that is not combat related or visiting a Starbase, I'd like to just go in my uniform and not have to keep un-equipping or equipping. I don't think captain Picard would visit an Admiral to receive a commendation while looking like Robocop and carrying a BFG. Nor would I.

3.
Compare Inventory When I look at things in my inventory. I just want to look at them, I don't always need to have them compared to something that's already equipped to my ship and appearing in random order on my screen. If I want to compare them, give me a compare option so I no what I'm comparing.
4.
Anomalous Objects and breaking missions. I've lost count of how many times I've gone off searching for that last anomalous object only to my find that my mission is now screwed and I have to warp out and back to start it again. Please fix this or at least if we're meant to go and find all this stuff at the end of the mission. Then can we at least beam back to the ship still orbiting the planet/station/asteroid and not immediately back into sector space.
5.
Auto-targeting can we have keys/buttons that assist in auto-targeting. Not everyone plays with gaming keyboards and custom keys. Some of us (ie me and that guy with the one eye in middle and only 4 fingers) play on laptops. Sure we have the ever helpful 'tab' key but more often than not that targets the ship I can see by the planet in the distance (all of 20km away but that's another story) and not the one that's behind me shooting energised particles of electromagnetic radiation (light people... light) up my TRIBBLE. My Mom said the sun doesn't shine up there even though I think it might :P
6.
Next week's Lottery Numbers If I win, I'll be you some stable servers. :P
7.
disable chat window Sometimes I'd like to disable this thing completely. I've countless times found myself announcing too all that care to read in between in offers of STOgold my screaming. 'aaaaaaaaaaaaddsswwwwwwwwwwssssdddd' etc. Either remove it or tell me which button it is that I must be randomly pressing by mistake so I can remove it or tape it up.

8.
Eight I'll think of more when I've had more beer. hic.
9.
more beer] See section 8 for reason.

Bind a key to walk. It's a push-and-hold though. (It's there.) No default binding.
Press "H" to holster weapons, and right-click on things on your character's equipment panel. "Hide from costume".
General UI improvements would be good.
Check your options menu under "General" or "Interface"(?) It's a bunch of radio buttons.
Not sure what you mean by 'bind'
I know about the 'H' button that doesn't take care of the armour etc. I should add that I just want to beam down in normal dress uniform when going to a non hostile place automatically.
They would.
I've tried the options. Maybe I should try some more but I think what my incompetence wants is missing.
As I said, armor and kits you can "hide" by right-clicking it in the equipment menu, and choosing "hide from costume".
