Denied extension requests[edit | edit source]

  • DiscordNotifications (GitLab ticket) - The code is not suitable for our platform, but we like the functionality. This is something we'd like to investigate doing ourselves in the future.
  • EditNotify - Configuration too complex for setup and maintenance.

  • FixedHeaderTable (GitLab ticket) - We like the idea of the functionality and will implement something similar ourselves.
  • GlobalUsage - Requires too much development work to get it working on our platform that we can't invest at this time. We can revisit it in the future, if there's a strong case for it.
