Hi

I just thought I'd mention that I've made and released a new theme for 4.7. It's called Fern, because it's got ferns in it.

It's a 3-column CSS theme which makes only the minimum possible number of alterations to Bluemarine. Its layout makes unaltered use of the output of Alex Robinson's One True Layout generator and therefore can be simply replaced by the site admin.

If you want fewer than 3 columns, it's not for you. And because of its fixed width, you will probably want to use a different theme (using sections.module, for example) in the admin section. That said, you can use Robinson's tool to generate a layout file which uses % values instead of pixels, which would remove the need to worry about admin overflow.

Anyway...

It's free, it's available, and it's yours to enjoy.
