• The HelpNDoc error I reported is a known problem. To be fixed in an update.
  • Turns out that the sitemap generator only looks for links to YouTube, etc., videos and does not include self-hosted videos.
    • Camtasia ticket asking for new feature

    • The number of inputs from TechSmith is being throttled by YouTube. They're working on that too.

    • Each colored dot (tri-color LED) represents the aspect of a semaphore arm. See similar diagram in "Pictures."

    • Space on the left will be used to show the CPU temperature and fan state.
