The Database Lookup step has a panel that occupies a lot of screen space and it is barely used.
On a laptop can be painful using the step if the screen has a low resolution.
The panel "keys to lookup the value" is not resizable and since by default has a considerable height, the panel which usually contains more fields (values to return from lookup table) has a very small size and it is barely possible to view a couple of fields at once.
I have highlighted in black the empty space that cannot be changed.
Ideally it should be possible to resize that space so that the panel below becomes more visible.
