In the latest version, we implemented 3D touch based cursor control. We recognize this only works on the latest iPhone models, and will keep the feature for non-3D touch enabled iPhones on our backlogs. if you use 3D touch, let us know what you think!Alisher commented
We spent a lot of time looking at ways to optimize for 3D touch, and found out that, unfortunately, third-party keyboards don't have the same level of control over 3D touch functionality as the native keyboard. For example, we cannot move the cursor up and down, only horizontally.
We'll certainly look into a way to make it less buggy. Thanks for your feedback!
We’ll take a closer look at this, thank you.Alisher commented
On iOS we tried something different: your personal dictionary is built in the background based on words you type and corrections that you edit. So, in order to add/modify words in your dictionary, simply type out the word completely, and next time it should be predicted. Let us know if that's not happening for you.
