+1 for percentile dice! There are workarounds using d10s, but it would be nice to have native support. What other dice types are we missing? More importantly, what are we missing that cannot be trivially implemented with a rollable table? For example, a d6 with special symbols on each side (scatter dice in wargames, for example) is simple to make a small rollable table for. Of course, a rollable table doesn't give you 3D dice, but priorities need to be set. =)
