@11assets colors would require a plugin, but you can have headings, etc with Markdown.
Change the post time tooltip to be more readable
I participate in the http://mangolassi.it community and just noticed that if you hover over the "replied about 18 hours ago" text, you see the actual timestamp. Great little gem. Can it be set to show something more readable though?
Just found this thread and wanted to say thanks for updating the hover text.
