Override with complete option when in the middle of the word
When editing an existing word and choosing the completion's suggestion, the rest of the word isn't deleted. Here's a screencast to illustrate: https://asciinema.org/a/3mbwu8vkpllcfwyvvxp9spt23
Sorry, This is how vim's keyword completion behave. I don't think I could fix this.
Seems that neocomplete does that somehow (if I'm not terribly mistaken...) :)
As a workaround, use vim's ce to delete till the end of the word and enter inset mode.
I wonder then, is it possible to detect if after the completion you are still in the middle of a word?
@for-coursera I think you could roll your own solution for that using autocmd CompleteDone and put it in the README as an additional script, this is SimpleAutoComplPop after all :P I'm a novice too but just an FYI
