1. Get Clip Studio EX. (Pro is ok, but you have a 24 frame limit, yucky)
2. Press New > Animation and set your statistics. 12fps is good. This will automatically make a Timeline for you.
3. Make sure your Cel Layers in your Animation Cel Folder are in their own folders.
If you do this, all future layers created by the new animation cel button will be in Folders. This will make copy-pasting information from frame to frame a non-issue.
4. Turn on onion skinning to see before and after frames
5. Animate!
Oh my god, I never realized I could use folders as cel bundles, this is life-changing for me.
