Delay before Suggestion dropdown [Bring it back]
I used to have a couple hundred milliseconds of delay in here. This was really helpful in some circumstances to allow me to do down a line of text adding tabs, spaces, commas, etc. (all kinds of things to satisfy my obsessive need for proper formatting). Without this option I now have to hit [ESC] each time to clear the suggestion box no matter how quick I move down, making this an annoyance.
