Sorry for the late reply.
1. Email notifications of new posts to subscribers (my blog, http://ukhumanrightsblog.com has over 4,000) now arrive from "wordpress.com" instead of the name of the blog. This is confusing and needs to be fixed.
Does this issue still happen?
2. The fade in/out haze feature is cute but should be optional. The sidebar features are really important on my blog and I want readers to be able to see them properly at all times. I tried to fix this via CSS but it seems to have returned today.
Unfortunately we don't have a plan to make it optional but you can force the opacity for the sidebar widgets with Custom CSS.
3. The 'edit' button is now at the bottom of posts rather at the top. This is a small point but it is annoying to have to scroll down to the bottom of posts when all you want to do is edit (not read) them.
I'm afraid to say we don't have a plan to chnage this but I can provide you CSS snippets to move the edit button.
