Add More Swiping Gestures to Keyboard

[stanskupienia]

Use Cases

Convienience in writing with many special characters. I hate long pressing and would prefer to rely on autocorrect heavily.

Proposal

First of all let me say that the app is great and works excellent in English.
My main language is Polish which has lots of ś ż ą ę, which require a long press. I don't like long pressing and have been using Fleksy keyboard. My method there is writing the word without special characters and swiping right relying on the autocorrect to make the word correct.

What I'm really asking is that You copy Flexy keyboard gestures.

1. Swiping right on the keyboard autofills autocorrect and adds space. Swiping 2 times adds a ".".
2. Swiping up or down cycles between different suggestions and applies them to the last word.
3. Swiping left deletes the space or the last word. (That one I like a lot)

If that is not possible I understand it 100%. There are lots of other important stuff in the pipeline, but I would like to see this become the best keyboard there is!

Point 3 is now duplicated here: #1244

As noted there, +1 for that functionality (as per Swiftkey).
