I need plugins for Edgewall Trac

I need the following plugins for Trac (if exist):

• Diagrams: Gantt and other;
• Export to MS Excel;
• Dashboards: control panels, monitors

Some pointers in order of your request with some remarks, citations from the plugin description or own experience if applicable:

• for Gantt diagrams there are actually multiple choices (in total absence of own experience roughly in order of likelihood of usability):
  • TracJsGanttPlugin by jsgantt, computed % completion, actively maintained
  • GanttCalendarPlugin - manually set % completion, month view for tickets, maintained
  • FlashGanttPlugin based on FusionCharts Free - just for milestones, not for tickets, seems unmaintained
  • SchedulingToolsPlugin, early beta, definitely unmaintained
  • GanttChartPlugin no dynamic, just YAML text block to Gantt markup processor, seems unmaintained
• ExcelDownloadPlugin - using this myself: works great, there's even i18n support on the way
• WhiteboardPlugin - not totally convinced here

More generally I recommend TracStatsPlugin to you for making a nice bundled view with navigation to sub-pages on topics (repo, ticket, wiki). It looks tidy and useful, and it has a responsive maintainer.
