3 fingers drag and drop

Using 16.04 with Unity I have a touchpad and I'd really like not to have to hold a button while I select text or drag & drop something nor the fake double click before dragging, I never found that handy.
I was able to configure this "three finger drag" feature on a Macbook quite easily and really enjoyed it.

I tried to configure it with touchegg but it does not work with Ubuntu 16 and with libinput-gestures but it does not manage the drag & drop.

All I need is to simulate a click while I have 3 fingers down until I release them.

Does someone know how I can achieve that ?

I know this is an old post, but I might have an idea.

You could try installing Fusuma, there is an explanation on how to install it on this thread.

It allows you to do custom commands for things like swipe and pinch. You might be able to configure it someway to do it with clicks? Or check the GitHub for a how to do it.

Hope it helps.
