I'd like autocomplete that I know what it's going to do. The current plugin is inconsistent, with better results when you type more slowly. If I hit "tab" somewhere besides the beginning of a line, I should get autocomplete options. If it hasn't pondered enough in the background to give me autocomplete options yet, it should unobtrusively tell me so. It should not insert spaces instead.
