Comment on: [Feature]: UI界面问题

Another thing — the Danmaku/bullet-screen idea is cool! I actually considered it when working on #133 , but given the complexity around rendering consistency and edge cases, I went with a more fundamental and reliable approach: hiding most UI elements in fullscreen to ensure the lecture content gets maximum screen real estate. That said, if there's enough community interest or the team decides to explore it, I (or the team) may pick it up in the future. Stay tuned~
