Replace "Show history on touch" with "Action on touch"

[algor512]

I would like to show on tap the history along with the keyboard. At the moment this cannot be done, there is only the option "Show history on touch".

I feel like it would be more natural to make tap on the screen a normal gesture, like swipe right/left/down/up or long press. This will make it easier to understand the settings, and allow you to set other types of actions (such as showing the keyboard and history) on tap.

Would you be able to contribute code?

I am not familiar with Android development, but I can try to implement this feature.
