I don't mind it. What do you not like about it and what would you change it to? Edit: I take it the F6 key doesn't do what you want it to then..
I and others I play with don't like it. Its all over the screen and distracting. I would change it back to having none at all if I could. Its like having a crack in your car windshield right in your line of view. or a pop up add that wont go away. Why no toggle.
Oh, that's a bit silly. I wonder of it's a design feature or they just don't know it comes back... If it's a design feature then its a rubbish one.
The only time I turn off the HUD is to take screenshots or to make precision landings (the toolbar gets in the way). Being an old fart, I sometimes forget to turn it back on. I have never had it come back on without hitting F6. I have noticed that after "sitting" in a chair, the toolbar is gone when I get out of the chair. It then does comeback when I scroll the mouse to select a tool slot. Beyond that, I don't understand the problem. A bug of some kind?
Only thing is HUD could be a lil more minimal with slimmer lines and have ability to customize the colors and from the total information to be bale the player to filter what to present on HUD.
