Windows 7. Seriously?

I am a power user of Windows. I like to fly around windows explorer and applications, and I do not want to take time to find where I'm going. I want things to be where I want them to be, and I want to be able to access them quickly. Here's where Windows 7 was supposed to make life easier.

Taskbar icons that can be reordered! Woot! That is wonderful, right?

Wrong.

I must insult the team at Microsoft that architected / designed / implemented this. It's as if their brains were on hold while they did this.

I've opened IE and Chrome. How difficult or important is it for me that IE be before or after Chrome. In all honesty, I can see the icon and quickly access the one I want. Windows 7 allows you to reorder them. Very nice.

I've opened three Chrome applications. They all have the same icon. I must read the name of each one, or look at the thumbnail more clearly to see which instance I want. Wouldn't it be nice if I could reorder those? Yes, that would be wonderful. But alas, Microsoft has deemed the reordering of instances of an application impossible!

Is there anyone who designed this who understands what they are doing?

This situation is most frustrating when working on multiple projects. I have a folder called 'hdl' under multiple projects. I work on multiple projects at once. I keep the 'hdl' folder open on each project at the same time. With Windows XP, I could interleave my 'hdl' folders on the taskbar, with my 'gvim' instances. So I would have on the taskbar:
'hdl' 'gvim' 'hdl' 'gvim'
The first 'hdl' and 'gvim' belong to project A, and the second 'hdl' and 'gvim' belong to project B.
Of course in Windows XP I had to create this arrangement manually. That is why I was looking forward to Windows 7.

In Windows 7, I can't create this arrangement. I would've happily given up on this requirement if at least I could order the instances. But I can't. Even if you choose to 'not combine' taskbar instances, they are still forcibly grouped together without the ability to reorder the instances.

For the first time since Windows came out, I have been forced to use an after-market application to enable me to work efficiently. Since I would encourage Microsoft to fix this, for those who are interested, it is called "7 Taskbar Tweaker".

I would much prefer to use Window's jump lists, and thumbnail previews, and all that jazz. But I can't because I can't reorder the thumbnails.

Allow thumbnails to be reordered!
Allow application instances to not be grouped together!
Perhaps even make it possible to detach an instance (like Chrome does with tabs).
