Not related.

Please describe the problem you're trying to solve

Right now there is just possibility to have automatic preview (sometimes slowing down operations), and not - activated by key, for instance SPACEBAR, which seems to be good option.

Would you be willing to contribute this feature?

• Yes, I'll give it a shot

Describe the solution you'd like

Some, coming from Mac, would love the possibility activate/deactivate it (preview pane) with SPACE bar as it is implemented on Mac. It could be handy feature for those willing faster operation if no preview needed.

Additional context

That could be settings option to gain sympathies from Mac users community.
