patch of Adds basic like state tracking using Atom Util · round #0 · pull #1 · whey.party/red-dwarf

Stores liked post URIs in the atom store, modifying the Atom store in the util to store both the Post Uri and the LikeUri, to allow for storing what posts were liked and allowing for deleting the like record.

Also modified the hasLiked boolean to be true if the post has a like string, or if the post exists in the Liked Posts Cache.
