Overall, great!

The app is great, awesome in fact, but it would be better if for a few tweaks.
1) Speed. When I go type type, say an apostrophe, the keyboard lags, and messes up my sentence and flow
2) Compact settings. Due to this, the microphone > text option on my keyboard is not available.
I use this often, and would like to see it back in the future.
