Every animation tool worth using is now aimed at someone who already knows how to animate. They are extraordinary at what they do, and they all ask the same thing first: install this, learn this, decide what kind of project this is, and then, eventually, draw. The gap between wanting to animate and animating has quietly become the hardest part of animating.
A flipbook has no such gap. You draw a thing, you draw it again slightly moved, and it lives. That is the entire mechanism, and it has not needed improving since 1868. What it has needed is somewhere to live that does not require a licence key, and a way to see the frame before the one you are on.
So Flipghost is deliberately small. A canvas, a timeline, onion skinning, and an exporter. Every feature past those four has to survive the same question: does this help someone finish a loop today, or does it help someone imagine finishing one? We have said no to a lot of good ideas on that basis, and the tool is better for it.
It is built by a small team that draws, which mostly means every feature gets used in anger before it ships, and the ones that annoy us do not survive the week.
