Also on another note, the zoom-in and out buttons don't work but I can zoom-in and out with the scroll wheel...

Yes the zoom thing is broken a bit, i'll fix that. As far as pasting html, you shouldn't be able to paste it because if you want to share code, it can be pasted as such but if you want to edit things, you can use the editor itself to do it (Editing Tools). If you click on the HTML button in the tools editor, you should be able to post HTML but not all tags will be supported for security issues.

A fix has been applied with today's updates TY for your submission!
