-------------------------------------

Proposal to consider enhancing this preso with the following changes:
* Restyle the menu as a pop-over.
* Launch it (and the data types pop-over) on single-left click.
* Provide hint text in the empty grid cell, such as "select type" or etc. Although I don't think we're doing this in the other cells...
I made a quick mockup, please let me know what you think.

(Future) To follow-up on a general point that you have raised [~karreiro] regarding places where we can provide more guidance through the UI. Maybe this initial empty table screen might be a good candidate? But for now, enhancing the pop-over could be a good baby-step. :

> * The {{UndefinedExpression}} grid "decision logic" selector (menu to select logic type: Literal expression, Context, etc.) currently uses a double-left mouse click to launch the menu. Given the menu is closer in spirit (and intention) to a popover menu - to provide a more consistent and predictable user experience it would be preferable to launch this menu on a single, left mouse click (will be covered by DROOLS-2910).
> * Re-design the {{UndefinedExpression}} grid "decision logic" selector.
