wao,,I check topics about keyMate again.. .
then need to ask some question 
Redave said,, ds timeline is cubic linear animation,
I think I do not have the way to edit curve of linear line in ds timeline,,
then,, KeyMate is non linear key frame animation, so that ,,
it means,
I can not tweak and adjust curve of movements between two key frame ^^;?
thoguh I know,, we can edit the curve of linear in animate 2 keyframe edit mode,,
(of course it seems useful I can change the value of each key frame in ds timeline,,
so I may not regret to get keymate)
and,, Go figure said,, there was bug, when use keymate with auto-fit,
then,, have the bug are alredy removed ?
now I download it. if I need send pm?
