Being a noob I am in a some what fresh position and fresh eyes on the whole mine-imator experience and I see the need for colour coding in some areas in the mine imator for one it would be good to have the colours of the rotation wheels movement in there respective colours for X Y Z so you don't grab the wrong one when you are unsure which is which, I know there are letters, but colour would make them stand out more.
And maybe a automatic left and right tab: Left leg Right Leg Arm etc etc in an LL and RL form.
Also the the tabs for grabbing parts, the area of catchment should be bigger for ease of use, even thought there not always visible .many times I have pulled at an edge to find it either doesn't pull it or it bounces back up without you noticing it do so.
Well that my penny's worth for now. and I hope you find this useful.
