FUTO has gone from tolerable to pretty great over the past year-ish. Sure, the (english) auto-completion still may not be the "best," but I generally find it better than my iPad auto-completion. Thou, my fav-features are pretty simple: the ability to pin dedicated action buttons like undo/redo/select-all, and direct control over my clipboard history. The clipboard does come with hard max limits of 100 items and 336 hours, but since FUTO is open-source, all one has to do is clone, patch, compile, and voila, unlimited clipboard history! And they say dreams don't come true.
