There’s also the full-screen editor — the window-looking button on the visual editing bar — that’s been here since 2.5. I think that view is often too wide, but it’s certainly there if you want it.

And the concern about horizontal space that I had on the months old build that I was using when I wrote this post have been mostly alleviated. Assuming no huge changes from the Beta 3 I’m currently using, the navigational sidebar is collapsable down to just the icons. In that view, the width is pretty close to what it’s been (though it’s certainly not bigger).

And I feel the need to say that the current state of 2.7 is quite nearly more useful than I thought possible. The Dashboard’s pretty great — choose where you want everything. And little things, like the ability to reply to comments in the admin area, are just icing on the cake of automatic core upgrades and the built-in plugin browser/installer.

One thing I will definitely agree with you on is the reduction of horizontal space, especially in the editor. I think the current editor (2.6) is a bit too thin as is. To see that getting even thinner is not something I’m looking forward to.

However, if I’m not mistaken, it looks like it may have gotten taller, which is nice. I would like to see a sort of full-screen view of the editor (or even better, an ‘in-theme’ version of the editor where you can edit almost as your users will see it).

It’ll be interesting to see everything that happens once it gets released. And I agree that it is great to be using such an ever-improving platform.
