All „Document“ pages of plugins should clearly tell, which other plugins are required for operation

  • Root plugins (no other dependencies) and leaf plugins may plot some forest picture.

  • Some plugins may exclude each other. In this case they may show relation to different roots at the forest picture.

    • E. g. Pade and Galene serve for the same audio/video conference purpose. Even if co-installation would be possible, would it be wise to do so?
    • Exclusion should be told at documentation.
