I believe I've found a couple of bugs, one with the MCE Editor and the other with the Motion Creator.
The first one is freelook_max_speed seems to be linked up to freelook_max_angle in the MCE Editor, causing the editor to save the the max angle value as the max speed. Currently I have to edit the MCE manually after making any changes with the editor.
The other one to do with the Motion Creator is a bit more complicated.
I've been trying to create a profile with left controller cw and ccw tilts in binding groups. When I assign one of these tilt gestures to a binding group they will work fine until the same tilt is assigned to another binding group. So for example, in binding group one I want L to be assigned to ccw and R to be assigned to cw, and in binding group two I want 1 assigned to ccw and 2 assigned to cw. When L and R are assigned to binding group one both actions will work fine. Now if I were to assign 2 to cw in binding group two both R and 2 will not work but L will work as normal. Now as soon as I assign 1 to ccw in binding group 2 none of the actions will work.
As far as I can tell this doesn't affect other tilt gestures as my profile works with left and right gestures in both binding groups.
