Because I just read some other question, I noticed a plugin that we did not install: the Case History plugin. I looked for it in the Plugin Gallery, but it's not there. I take it it's an internal part of FogBugz that is installed by default?
What will happen if I delete the plugin?
The same applies to Reporting, Reporting - Additional Metrics and Custom Field Breakdowns.
Is there some documentation about the new internal FogBugz 8 plugins?
