Hi @Milk2bad thank you for suggesting more features! Please keep doing so.
I definitely try to hear everyone. My time is very limited, that's why I try to add features that are not too complex or I feel it can help a huge group of users.
I am not an artist myself so adding anything that requires tweaks or new assets usually takes me a looong time. If you can provide the blood marks you mentioned, I can definitely add them.
About hand movements, would be super tricky to add them to this app. Currently it simply stack a bunch of images to create the character there is nothing dynamic. Adding this would require a huge effort and would probably be an entire new app, I can add to my to-do list but very low priority (unless if I receive more requests to add it).
Thanks once again, hope I could be clear and it's not that I don't want to add it but I have to choose what to add wisely.
