- Diff view changes -- Only show pool description changes in diff view -- Conditionally render diff link when applicable values are changed -- Conditionally show diff view sections when values are changed - Show renames on index view -- There is plenty of space -- This wasn't shown at all for wikis -- Having to navigate to an alternate page is unwieldy for pools - Show "posts" as a status on pools -- This is so all changes among versions are quantified as a status - Standardize diff/index titles
