Group, label or organize the repository list?

It would be awesome if we had the ability to customize our repository listings more effectively, for example:

• Select which repositories are displayed at the top of the repository list, or more prominently than other repositories. For example: I've got lots of little individual dotfiles repositories 'dotfiles-vim', 'dotfiles-sublime', 'dotfiles-bash', 'dotfiles-zsh', 'dotfiles-tmux', etc. They clutter up the page, and I'd like to make it easier to find the repositories that are interesting.
• Allow users to group repositories (potentially by labels) to unclutter their repository listings. For example: If I have 20 different 'dotfiles' repositories, organize those into a single group or category to unclutter the main repository listing. Perhaps have this category 'collapsed' by default, or shown in a 'sub repository' page.
