I'm with everyone else on this and raincoaster said it very well.
Given the number of times I click between blogs each day, I have to say that the additional difficulty switching back and forth is extremely annoying. I really don't like it.
1. Hear! Hear! I find the right to left change of the former "Blogs" drop-down menu to be counter-intuitive and annoying. I used to be able to switch between my blogs quickly and now that switch is annoyingly slow.
Better, right!? Now on the right hand side of the admin bar where your Gravatar is displayed, you have easy access to your user profile, all the blogs you can contribute to, and all the comments you’ve made across WordPress.com:
2. Wrong. I do not comprehend how the duplication of buttons found in the left hand Admin column and now in the right hand drop-down can be considered as simplification? I find the duplication of buttons to perform functions in the new drop-down on the right that I can already have in left Admin menu column to be unnecessary. Does this mean the left hand Admin column is going to be eliminated?
3. Thanks but I don't need to see my avatar in the right-hand drop-down "box" in fact I don't display avatars at all in the comments on my front page Recent Comments widget so my page loading time is quicker. Now I have an Admin section where everything is loading SLOWLY. I don't know if removing the gravatar would speed it up or not but I don't need to see me when I'm switching from blog to blog so I consider that addition to be unnecessary.
3. The page loading time in my Admin section used to be quick and now no matter which button I click the page loading time is annoyingly SLOW. I spent a considerable portion of my time yesterday clearing my browser cache and cookies and rebooting my computer to no avail. I'm on XP using Firefox 6.0.2, my Flash is updated, there are no known issues with my ISP. I even unplugged my router and then reconnected but that did not speed page loading time when I logged in again. I deactivated Zemanta and that did not help either.
4. In response to my iPad users' requests I deactivated the "follow" button at the bottom of my blogs and deactivated the mobile theme function. Apparently, they have trouble leaving comments due to that little "follow" pop-up.
