I hate the over dark colours and lack of choice but can live with that now.

The homepage is much too busy and could use tabs for various functions.

The biggest problem is with the individual channels.

We have TOTALLY LOST CONTROL OVER OUR SUBSCRIBERS. Unless we save every email that announces a new sub there is no way to know who subs us.

We used to be able to check out our subscribers in the addressbook or on our channels (if visible). We can't now.

There is no way to block a subscriber unless they comment, or leave a message, or you find their channel. There are a lot of stalkers that use one channel to sub and another to harass people. People I know routinely block the more notorious channels.

You still haven't added a block button to unavailable/hidden channels. This format is used by predators and trolls.

I want to be able to check my subs in my addressbook.
I want to have the option of showing my subs.
I want to be able to block hidden channels without having to jump through hoops to do it.

If you fixed these three points I would support the new layout.
