Add haptic/vibration feedback when holding delete and moving cursor with space

Is your feature request related to a problem? Please describe.
Not a problem, but it would be a nice addition.

Describe the solution you'd like
Ability to toggle vibrations for these events.

Use case
Whenever one holds down delete or moves their cursor with the space key.

[e-t-l]

I would also add a request that triggering the long-press of a key makes it vibrate a second time, to help users differentiate between a normal press and long-press of a key.

The vibrate on slide (delete and space) function is something I've very much missed from most of the keyboards I've used. I hope it could be implemented soon as it's probably not the most technically complex of features

This, please.

I would love to have haptic feedback when pasting item which appear in main screen just after coping something

It seems that heliboard now does haptic feedback when using the spacebar to move the cursor. Great work!

I think if this PR gets implemented, this issue can be closed, no?
