MDI vs SDI

I don't know if anyone is actually reading this or not, but...

Currently wiFT uses an MDI interface. A separate child window for things such as search results, downloads, uploads, etc.

It's been suggested that MDI isn't so hot. Personally, I like the setup, but it seems the more UI articles I read, the worse MDI gets.

I'm interested in outside opinion and comments on the subject.

Please feel free to post in the forum or email me directly if you care to have any input.

Thanks.
