Every fluid sim setup has the same tedious step: keyframe the domain hidden one frame before the sim starts, visible on the start frame. It takes about 30 seconds but you do it every single time.
I built a small addon to eliminate it. Select your fluid domain, go to Physics > Fluid > Auto-Visibility, and click the button. That’s it. The panel even previews the exact frames before you commit.
