Someone in comments suggested to allow users to customize a button to set an action to. No problem.
Now it became possible to select Home, Recent Apps and Back keys to perform each others actions. For long and short press.
Don’t know if it is convenient to select a key and an action in such a dialog.
We have almost 200 downloads now and 30 active users. Will see how customization abilities will affect it.
Just for fun added an in-app purchase for remapping more than 2 actions. It would be not fair if it was impossible to switch Back and Recent Apps for free, doesn’t it?
