I was surprised on how well I was able to just drop my ideas into this program everything super easy to read and if you have any issues as if the shortcut is not to your preference or there is another quicker way of you in putting something it's also customizable and all of this is free. And doesn't take a lot of space from my computer so it's easy to run it runs fast you can throw ideas in there left and right fairly quickly...

Work with this program for now as I am currently not collaborating with anybody, but it looks like you can easily read and comprehend what the animatic is doing if sharing a project...
