If you ask any real thief, what does he need in his job, it would not be an acrobatics nor some wild jumping, becouse it is too noisy and noticeable. I don't know what movements are already included in TDM, but I thing that the most appropriate improovments would be in a creepage. I mean some silent and crafty ways how to get over obstructions without any useless exhibitions. For example this skill is cool. Or lower down from wall to get closer to ground was many times usefull even for me to get down from height. I don't know how to express it with my english. I mean this process, but reversed. Also crawling on belly or crawling through a thin manhole would not be bad. As well move hanging hand over hand along a horizontal rope or ledge is wery thievish, but I guess it might be a problem with mentioned invisible hands. Anyway the last video on TDM webpage demonstrates, that those moves are already very impressive.
