I was trying out the new theme (nice!) and found that the sidebar overlaps with the footer when only a small amount of content is present on the page (like the ‘hello world’ post).
This should not often be a problem, but I thought I let you know.
I have just checked and #23504 is about this issue. Check it out!
Like I said it shouldn’t be a problem in most cases… but it does not look very nice. And using dark letters the sidebar menu becomes unreadable.
