1)Uo fiddler converts many imagens to a wrong color... like this image

2)when i try to add one image to an empty animation slot... the color of image is converted only to white tone

My suggestions:
1)you can add an option to add MANY IMAGES at the same time to an animation... for example.. i must add 10 frames of animation to one slot... but with "add" options of anim edit i can only add one frame by one... an option to add many frames at the same time would be great =]
2)you can add an option to put all animations of the same slot at the same cordinate.... it would be GREAT...
for example: my walk animation at down position has 10 frames... and all frames at the same cordinate...but i must put all these 10 frames at the same cordinate one by one.... this is boring..
3)just look at image

With UOanim arrow.. it is easier to view where you are going with animation.... because with uo fiddler arrow you dont have reference where you are going with image in X center... because the image will walk in this positions <<<< or >>>>> ... bahh i cant explain this ...
Ok.. this is my suggestions... sorry for my bad english... =].. cya
