Try Titan Panel:

http://wow.curse-gaming.com/en/files/details/618/titan-panel/

It puts a couple of nice slim bars at the top and bottom of the screen which display all sorts of useful stuff including co-ordinates, your armour's durability, your bag space, money...

I tried to use a potion last night in an instance to avoid dying and the game came up with an error with Atlas. It wouldn't let me use a potion (Ignore did nothing) and when I Disabled the add-on it kicked me from the game for a few moments; nearly wiping my party.

maybe it's me but after the last patch titan panel isn't working anymore as intended (though I d/led the newest version): the bottom bars and the pet bars overlap the chat window so it's impossible to read the last 2 lines. I tried I think almost everything in the options but it didn't work.
so I found koordinator: small and easy. in fact it has the only option that really interests me, that is, showing player and mouse coordinates when you see the map

Yep, make sure chat is unlocked in your interface options, then right click on tab where it says General and select unlock. Then you can move the general chat window.
