Enable Single Window Mode in Acrobat 9

Question

Please re-enable the Single Window (MDI) Mode in Acrobat 9 as it is an un welcome user experience of having dozens of Acrobat windows open in the taskbar. I can suggest to have either of the following:-
1. Give an option to the user whether to open the multiple or single Acrobat windows as is the case with Acrobat 8 with "Preferences->Documents->Show Each document in its own window"
2. Introduce tabbed browsing in Acrobat similar to the one implemented in IE 7.0 to have multiple PDFs opened in a single Acrobat window.
Thanks,
Atin

"In Acrobat 9, we dropped support for MDI."
Not a good idea!
Now, please let us have it back.
You have to realize that you break peoples work flow with this ill-thought-through change.
"Feature Parity with Macintosh was desired" -- Not a valid argument from a windows-user point-of-view
"Making SDI default, but still providing MDI in version 8 was done to start the deprecation of MDI." -- That trick didn't work, re-enabling MDI was the first setting I changed in Acrobat 8 (and actually Acrobat 8 broke so many other things, I quickly reverted to Acrobat 7).
"Microsoft advised that to work as good as possible on Vista, applications should avoid MDI." -- Microsoft is not the user, we are! Besides, many W7 users reset their desktop to classical.
"This increases the cost of testing the product and the cost of fixing bugs." -- So it's easier on Adobe, but bad for us... is that an argument at all?
"in a world where larger screen resolutions, multiple monitors and the need to see multiple documents at one time has increased, SDI mode offered higher benefits." -- As someone else already mentioned, on a multi-monitor system SDI is flawed.
So... now that you consider reverting to MDI, please also introduce tabs, that's the only thing MDI applications typically lack, though things are improving.
EDIT: People been asking for this since 2008! Come on, already...
