My PNG artwork files are built so that they can be perfectly sliced in Unity or other Dev programs without having to make any manual adjustments or edits. If you're having trouble I highly recommend you look into it. Manual cut and paste is the clunky approach. Here's a tutorial showing how its done. You can see that there's no clean way to annotate the sprite sheet and a separate legend is ideal.
oh yeah and they work great i am using tiled, not cutting them individually have also used Unity the formatting is not a problem at all its fantastic work the issue only arises when i am trying to parse where one animation ends and the other begins it isnt a huge problem and i still would urge anybody who these interest to purchase these it is the visual equivalent of no punctuation and no capitalization in a paragraph its okay though because those things are in a separate file
