My Eclipse installation has an unfortunate habit of accumulating 'contributions' in the lower part, below the editor, which apparently do nothing, but can't be removed or properly resized. Unless I'm aggresive about removing other, more controllable, parts it ends up on two rows, which is extremely annoying.
Even though it's on one row, I do get useless contributions, right in the middle, between 'Smart insert' and the calendar entry.
How can I identify and get rid of them?
