Hi. Sorry if here is not the appropiatte place for suggestions. I'd like suggest add support for more file formats, such as exr, tiff, etc. Specially open exr , which its sdk is totally free. I think that open dain-app to vfx industry could be highly possitive for this project. Working only with mp4, png's.. is very limited. Only adding exr (nowadays a standard) , will make possible open the use of dain app for more exciting projects.
Thanks.
