It's awesome to know that SwiftKey can switch to Incognito mode automatically in Chrome/Firefox incognito tabs. But there's an issue.
The keyboard theme/UI for the incognito mode, does not show Accented characters. This causes serious problems while typing or want to type fast.
Solution : 1. Implement the feature, to show all Accented characters, custom theme in incognito mode (just don't track the typing, and that's all).
2. Give option to turn off Auto incognito switching.
