Make git fast again - Git is awesome software but it is quite slow when using it to manage many small files. For example I have 17000 markdown files in my website's data repo and the git client is unbelievably slow and often unresponsive. I wish ghis could be improved. That's a big issue if you want to manage a static site with git.
If you want to make many people's lives a lot better consider improving git to make it better at handling large quantities of small files. #
