Hi everyone! I just released my first plugin and wanted to share it here.
Web Behavior Preview opens a Figma page as a real scrolling webpage: sticky headers pin and stack under each other, sidebars ride along with the content (the Airbnb-style pattern that native sticky can't do), bottom bars push each other up, and the clicks, hovers and overlays you already wired in the Prototype tab come along. One button exports the whole thing as a single self-contained HTML file you can send to a client instead of explaining the behavior in words.
Free, no network access, nothing to configure.

Playground file to try it on: https://www.figma.com/community/file/1676368484360559450
Would love feedback — especially if you hit a layout where it guesses the behavior wrong.
