// BUG: Sometimes we only see old posts, and don't see the feed. I believe this is the result of loading in from a thread or profile post.

// Should all be lowercase, words to filter out
const keywords = ["skeet"];
// If fixUI is true then certain elements will be expanded to 100% of their container, the "New Post" button will also be adjusted to be on one line.
// This results in less broken text and a nicer new post button.
const fixUI = true;
// In debugging mode a lot of text is output into the console, and posts are red instead of hidden
