Yes, it's always hard to have something perfect when transform small pixel art also the big issue I find in Spriter (pixel mode), there is a lot of jittering due to their pixel approximation (fixed in PixelOver).
1) There is auto keying, it's activated by default, ones a track is added modifying the property will create/update the key.
2) Noted thank you for the feature suggestion !
3) Yes, I see a more visual way to choose the image frame.
4) It works for both axes. Basically without shift x and y have same ratio and shift makes x and y independent.
5) Mmh if it is by body part and aligned with its transform we can have issue that what we modified at a certain transform will affect negatively in another transform. But yes in any way if I implement a layer to paint over, adding a way to modify the images of each object can also be possible.
8) Ok I see the issue now. Will be improved in a future update, thank you.
9) Yes original line should be replaced with a computed one, it could be possible, not easy but possible, I'll keep that for a future update.
Currently it's only possible to use gradient instead of color and put semi transparent color which can be reindexed in the given palette (some semi transparent black for example)
And gradient can be in child of an image or bone to follow the transform.
10) There is already a way to switch between seconds and frames but should be improved to put all the position and length inputs to frames and not just the timeline.
Noted for the new shortcut, to move of one frame, thank you.
11) Yes good idea about the auto indexation !
12) multi points control to vertex, noted, thank you
13) Gif export already added. You can change the extension :
But I think for a future update I'll separate folder, filename and extension in different inputs, so it will be quicker to switch.
14) Yes, in shader filters there is polish inputs to remove alone pixels.
15) Yes maybe it could be applied in a more general scenario than just the light. But yes it could be nice for a future update.
16) Maybe this can be imported in another layer ? I don't think we need something special for this.
17) Yes there is some way to improve the actual resamplers. I want for example to implement Content-Adaptive Image Downscaling :https://johanneskopf.de/publications/downscaling/supplementary/pixel_art/index.h...
Seems a very good compromise.
Thank you again for your time to give all these feedbacks and suggestions, that's help a lot to improve the software !
