Next unit button that picks from all the units, and another button that "Moves the unit" in the selected direction would be nice.
Interface buttons plus keyboard shortcuts, I don't like keyboard shortcuts with no button attached to the same feature.
On a related note, Could you make the explore button more obvious when it has been selected, by choice or accident.
YES!
Although I never really use it

I do click it by mistake sometimes.
Sincerely
