Thanks for the feedback. I created the poll so I'll be sure that when we create the Bounty we are clear in that the underlying API is what we are looking to improve.
I don't follow - it is /not/ clear to me which underlying API it is that will get implemented by voting for "sublime-style mini-map".
Possibly this will answer your question? http://www.reddit.com/r/vim/comments/1yqqhl/bram_responds_to...
I'd prefer if they could be renamed to "Fetaure X which enables e.g. sublime minimap" and dito for autocomplete.
