There are two annoying things with the Smart Keyboard (and possibly any iPad-connected keyboard) that I otherwise like very much. First is the language switching. When I press the language key (the one with the globe icon) and highlight the other language, if I start typing without pressing the return key (like you would on a MacBook) the first pressed key will always be from the previous language, and change only on the second press. The second issue with language changing is the weird toggle mechanism between languages. Let's say I have three keyboards - English, Emoji and German. Pressing the language key to access German from English will go like this: English - Emoji - English - German Requiring me to press the thing three times just to switch to the other language. Even if I use the up/down keys, it goest first to Emoji, than back to the previous language, than to the desired language. And combined with the fact that the first key press will be wrong (as I said, it will type in the previous language) I will regularly have to press the language key 3 times, than press a key, then delete the key, then press it again in the correct language. This makes switching while typing to access a special key on the fly really problematic. My second issue is some weird capitalization that's going on. Type a capital letter by accident for whatever reason, deleting that letter and typing it again will use the capital letter again, even without the shift key. Try it - type a capital letter (by holding the shift key), then delete it, then type it again without the shift. It will still be capital. And no, I'm not talking about the beginning of the sentence - you can do it mid-sentence or even mid-word, it does the same. Annoying.
