Pinned Lists + Private Lists

[Zanger67]

I've been using Lists to sort and categorize repos for myself and others but it would be great imo to have a way to either pin a few of the lists on the $\color{yellow}Starred$ tab.

Namely, I have "Current Projects," "My Projects," and "Hackathons" as the main lists that I use for others' reference, while the others are just for sorting and personal interest. I've linked them to my Readme but it would be nice to have a setting there too. What I'm noticing is that when I star new repos for self interest for instance, since the default tends to go to sort by most recently updated, it'll be knocked down the list of lists.

Being able to private lists would also be great especially for my misc. lists such as "interesting" which are things I want to look into and read into or "Class" which is just full of private repos hence appearing empty.

TL;DR:

• Private lists (for personal sorting)
• Pinned lists (for starred repos tab -- even just a few for key lists like current projects)
