I don't like your new interface. The old interface had its problems, but I really don't like the new interface. Since your "feedback" systems won't let you see what I really see, I am laying it out for you here (note that clicking on the screen-shots will provide a full-size view of what I see):
What I like: The font is compact, and it is one that renders great on all platforms (Windows, Linux, and Mac alike). It displays quickly and the display is used more efficiently than the new interface. Actions are simply text links, and are easy to read and find. They don't take a lot of space on the display, so a lot can fit cleanly in a small space -- a small space that happens when you use a netbook, or use a portion of your display for a web browser and other parts for other items. I also have my browser in a "portrait" configuration, since I view it like I would view a piece of paper. The chosen colors are easy to look at (are not overly bright).
What I don't like: Stuff goes off the right-hand side of the browser display. Because there is a lot of waste on the left side, it becomes necessary to horizontally scroll. Thankfully, the horizontal scrollbar has not been removed as seems to happen on many of Google's new products. I don't know whether they do that purposely, or it happens because they confuse the browser by forcing the display window to be a certain size.
What I like: Less horizontal scrolling. I think someone must have heard me when I complained about this, and I do appreciate that. Some of this was accomplished with drop-down menus. If these were done using the default browser rendering and, perhaps, text cues, then it would actually work nicely.
What I don't like: Let's start with the simple...the color of the page is blindingly bright. The old interface offset some of the white space with some calmer tones to make it easier to read in a variety of room lighting situations. I don't like the graphical styled buttons and drop-down menus. These take up way too much space on the page - they were obviously designed for a screen with much higher resolution. On a smaller display, it's obnoxious. The font that is used for the larger text is ugly, and again, way too big. The indentation and wasted space on the left hand side of the display causes information to the right of that to get pushed down smaller. Why are you indenting this? What is the purpose for wasting space on the left hand side of the screen for a "New Blog" button? Again, this compresses useful information - about my current blogs - on the right side of the display. Do I need to have a language selection on this page? Shouldn't this be part of my Blogger profile? Why not put creating a new blog up there, where there is plenty of space, and allow the blog listings to take more space on the dashboard?
Seriously guys ... you want me to go to this new interface? If so, I can't blog here anymore. It has become completely not-fun. I really wanted to send this all to you, but you don't have a feedback button that allows this much feedback. So here it is. Hopefully, you'll encounter this and see it, and it helps you to improve the service. Unfortunately, like everything else I've seen of Google, it probably will never change back. Sorry, but I don't like this new style. It doesn't work for me.
