I think this is easy to implement (no conflicts, you just have to add something). Please consider it for an upcoming release.

Currently, there is a single description for a project. It is displayed in the projects list as well as in the projects overview tab.

Compared to now I'd like to have another description which is only visible on the projects overview tab. There I could give some more overview then in the project list. E.g. I'd like to point to important wiki pages or other interessting things. Those things could be navigated to anyway but I'd like to have some quick links for the most important pages. And those things shouldn't be visible on the project list. There the shorter descriptions are sufficient. Other things would be too much information.

The current description could be the 'Teaser', the new description the 'Project details'.
