I have noticed that the Rig presets selection in the Pose/Animate tab is not saved in mhm files. It would convenient if it were. There are times I need to load the file, tweak it, and export it. When I do this I must return to this tab to select the rig with every mhm load, and it is easy to forget to do this.
The MakeHuman version I have noticed this in is 1.0.1.
