this is only my personal opinion, not trying to attack Drawn or anything of those sorts, i love so much here you can't even imagine, and i'm grateful for the almighty creator's work, but i've just been put off by this for a long time, since the beggining, and it has bugged me and bugged me every time i drew. i feel like the onion skin's opacity difference between the main and the 2nd frame is too small,,, it's right in the uncomforatble amount of difference in opacity,,, aaaa i often have to trick the 2nd level of onion's skin opacity to being the 3rd, or i can't even work at my animations seeing what i'm drawing idk if you know what exactly i'm talking about, but it's just like, the main layer is 100% opacity, and with multiple layers and onion skin, the frame you had switched on before your main, current frame has less opacity. but i think it would be so much better if it would be still a good amount less of it,, idk if it's just me that's really annoyed by this,,
