In a lot of programming, frame 1 is referred to as frame 0.
While this has no bearing directly when spriting in Aseprite, sometimes when programming I need to visually reference the timeline of a sprite I made. However, because frame 0 is frame 1, I always have to think “Okay, so if the action starts on 45 til 67, then it’s 44 til 66…”
It’s not a big deal, but it does lead to typos here and there, and it would be convenient if there was an option to make the frame count start at 0.
