I am very new to vendetta online and have noticed that when a mission is completed, it stays in the PDA and there is no way to hide it. I think it would help a lot if there was a way to hide missions automatically if they have beeb completed. There should also be a way to unhide the completed missions where the title of the missions would be crossed out. Please discuss.

They aren't hidden since you can do them again.
Most missions are the generic kind so it only makes sense.

It's also used for recalling purposes.

you can always use your mission log for this, but since many missionsare generic...mining, escort...etc...etc...actually getting rid of missions youve already done would be foolish.

How about a compromise, as I understand the need to clean up the missions list greatly. Why not have sections for different types of missions instead of one long list?
Such as Combat, Escort, Mining, Manufacturing, Trading and so on. Whenever there aren't any missions that fall into the category, the category disappears.

on and a section for completed missions and non-completed missions (almost like a buddy list) where mission could appear in multiple categories.
