Make it harder to accidentally hit function keys like caps or backspace
Same goes for the backspace /delete key and Enter /smiley button. Move them apart. Its so frustrating trying to delete words only to end up with a mess of "L's", faces, & line breaks.
Same as previous commenter, I constantly end up with unintended caps and backspaces. Though I'm not sure how I would fix this. Perhaps make those keys smaller, I'm not sure. I don't see where they could be relocated.
Oh yeah. I constantly end up with cap A on the left and line breaks on the right. If the cap key were able to be long press activated it could deal with that. Otherwise all my rNdom<example typos drive me nuts
what's worse is SwiftKey's concept of scale. predicted words area should be thinner. letters should bea little fatter. Voice button should be huge. Delete needs to be smaller & relocated. shift/caps should be smaller, etc. etc. etc.
The concept is great. The design is retarded
