Denote feature flagged features in the app

[corywatilo]

We are constantly yoloing new features behind feature flags in "team 2". But it's really hard to keep track of what's internal-only, what's released to a handful of users, and what's public.

Given how many people we have joining, and how many new features are getting pushed into production, it would be worth having a visual indication internally of a feature's status if it's not public.

This is a tricky thing to solve since there are different ways features are exposed in the UI. Here's a few ideas:

Internal-only

Icon with tooltip

Changing text color

In cases where there's already an icon, it'd be funky to have two icons, so here I changed the text color to dark blue. I'm trying to walk the line between being obvious without being obnoxious, especially since I'm assuming some of this will potentially be seen by customers during demos.

Limited release features

I was going to try to use a present icon to indicate beta features that are selectively rolled out to customers. (Here the Doctor tab isn't GA, so I added a green present icon to its right.) This doesn't look great, so we could always change text color here like mentioned above, or maybe do a dotted/dashed underline.

Could also potentially just color the existing icon differently in this case (to green).

Open to ideas!
