This is the traditionalist in me talking, but currently, NeoLemmix takes on the approach of Lemmings 2 and only shows available skills with at least 1 available use (or 0 if pickups of it are available).
I would like to request that the option of showing 0 of a skill regardless be allowed (with the characteristic blank number display rather than actually printing the number 0). The reason being is that in some levels, especially those using the traditional 8 skills, the lack of a skill is just as important, if not more important, than what you have available.
The examples that spring to mind are "The Crankshaft" from the original game, where having no Bashers is quite important (you have 10 of everything else), "Heaven can wait (we hope!!!)", where you have no Blockers (you have 30 of everything else), and "A break in the pillar" from Revenge of the Lemmings, where you have no Builders (you have 3 of everything else).
