Grav8 has a brand new theme! (obviously)
There's new features to improve the user experience, including ajax posting, modal for posting threads, a personal file manager to upload content, a dark theme (under Settings) with a few other theme options, and a bunch of other stuff you'll have to browse around to see.
Some features not yet implemented into the new theme include: sorting, previewing, and a few pages in the sidebar leading to a 404.
My hope is that Grav8 becomes a very easy to use platform for discussing S&box and sharing resources. This new theme is a big step towards that goal. It may not be perfect, and there's a lot of work to be done yet, but as with any software, iterate, improve, iterate, improve, etc. These things take time :)
Oh, markdown just wasn't cuttin' it so posts now support html with a WYSIWYG editor. If you find any bugs or have suggestions/feedback please share!
