Persist user preferences of React DevTools when debugging with Flipper

Description

When I am debugging my React Native app using the React DevTools in Flipper, I like to change the settings/preferences available, in particular the component filter to remove components I don't care about so I can locate the component I'm after more easily.

However, when the app is being reloaded, the values of the filter (amongst other preferences such as theme colours) aren't being persisted like they do when you use the same tool in the browser (say Chrome). This is a minor inconvenience as I'd like to not have to set the filters up again each time the app reloads.

Apparently this is a known problem due to the lack of a synchronous persistent storage API available on React Native from this conversation I started with @mweststrate @bvaughn @rickhanlonii on this Twitter thread, and I've been encouraged to raise this issue officially so it can be properly tracked and see if others are interested in this feature/solving it etc!
