[EN] Download manager in Internet Explorer?

Several times I hear request to implement download manager in Internet Explorer as Firefox users can experience for some time already.
I think IE-Team is the place to find proper answer to that request but I in this week I observed interesting thing on my Windows Vista and IE7.

I needed to download several virtual machines and these files are huge as you know. It took some time and my network wasn't stable in-time.
I've got several timeouts which are good reason to add myself into that request of download manager with continual download feature.

And here we go.. When I got that download timeout from download.microsoft.com and tried to re-download the file it started from the place it'd stopped before.
I checked it several times (gosh, today my internet connection was just rubbish) and it doesn't look like single-accidental-noone_knows_why incident.

Looks like it's some kind of feature. I downloaded huge files several times in the past but I cannot remember these problems with timeouts so much to recognize that it's normal IE's behavior.
I made additional test. I started download, waited some time and then I manually clicked "Cancel" button. Then I clicked the same internet source file to download again and here we go.

IT CONTINUES FROM THE PLACE IT'S STOPPED.

Uber cool even if not clear to the user but still I'm not sure if it's a feature or a bug-feature or something I cannot understand. Even though I'm happy because I could successfully download those damn files :)

Can you anyway tell me if you found this IE's behaviour too? I'm really curious! Tell me! :)
