Here's an example. The width of the "all tabs helper" view is the same as before. But the new sidebar adds 88 pixels of extra space, which is closer to 100 than 50. This area also cannot be shrunk - you can only change the selected view's width, but ...
The new sidebar is about 100px bigger than the old one - this is significant, and this space on the left is mostly empty. I wish you could collapse it entirely to leave just the selected view, like in the old version.
