I just love auto-complete. Software is much more fun when it sort-of reads your mind.
I don’t want software to just keep a history of my past usage. I want it to actually suggest something based on it. And do it un-obtrusively.
I don’t want to browse through a huge list of items, or enter a search term exactly before getting to see the result. Incremental search is nothing new—VIM had it since 2001. Emacs even before that.
And for goodness sake, tell me I’ve made a mistake in entering data as soon as I’ve made it. Before I submit it. Do-overs suck.
Computers are fast—they should work for us people. Not turn us into glorified data-entry operators.
