Sidebars

I have a small question involving sidebars and widgets. I’m working on recoding my themes because I found imperfections that big me personally and found a way to fix them by redoing them…but some I may have 2 sidebars and some one…is there a ways to reorganize the widgets by theme, or is the widget thing in the admin panel just a set order for any/all themes installed?

As an example, the one theme I’ve gotten done tonight, which is a tables layout featuring photos of Shannen Doherty, I have it set with 3 columns. Left: Search, Networks (a badge linking to my FB and Twitter) then Archives; the center is content and the right is the themes list.

The themes I choose to have 2 sidebars the themes will be a list, the ones that only have one bar they’ll be in a dropdown….

Now, can I organize the widgets by theme, or would it be easier to just have all themes with the same amount of sidebars with the same order?
