It would be great if a project homepage would:

• Render any README.md file in the main repository folder on it's homepage instead of a 'description'. (or even better, support multiple md docs within the repo to have per-project documentation)
• Show the diffusion browser (i.e. recent commits, branches etc)

This would provide much needed integration between Projects and Diffusion. Currently the only way to relate a project to a repository (or some portion of code within the repository) is to manually put a link somewhere on the project homepage. This is a very thin link as it will take you 'out' of the project and to the diffusion browser. So lots of back and forth.
Better integration (a la gitlab or the like) would be better
