I'm working on an extension side project, and I need some help
I was building a Chrome extension to add VOD chapter navigation to Chzzk (a Korean streaming platform), but the platform officially launched the feature before I could finish — so the project got scrapped. The chapter feature works essentially the same as YouTube chapters — AI-generated segments shown as markers on the progress bar with titles.
Rather than abandon it, I'm thinking of pivoting to user-defined bookmarks — letting viewers pin timestamps with personal notes while watching VODs.
I have a rough idea for the UI but I'm stuck on the progress bar area specifically. Should bookmarks appear as pin markers directly on the scrubber? And if so, how do I handle overlapping pins when multiple bookmarks are close together?
Would love input on interaction patterns or examples from other tools that do this well.
