Clev, Scramble Discord

4. No Button to go to the Reddit Homepage

5. There is no link to the full rules on the sidebar

3. The Filter List for video games on the right leads to
https://www.reddit.com/r/respectthreads/search?sort=new&restrict_sr=on&q=flair%3Avideogames
instead of

2. So I just posted a RT, since I've got RES while on the submit screen I could see a preview of what I'm about to post to make sure I got the formatting right. Only on here, that doesn't work, specifically headings don't work.

This is because the CSS specifically hides h1 elements, but only while on the submit page so it works fine elsewhere. This is to hide the submit to /r/respectthreads text either here or here. Could it please be changed to just hide those in this case? The relevant rule is this one
.submit-page .content h1 { display:none; }
To hide just those two mentioned you'd use .submit-page .content > h1, .submit-page .submit_text h1 as a selector instead, the former part hiding the first and the latter part hiding the second.
