I guess Microsoft would suggest you go with Excel 2002 with colored tabs.
Multiple layers of tabs is not available in any version.

My feeling is that colored tabs have nothing or very little to do with organization.

You can name your tabs so that they can be organized by sorting them.
ie. k.key words, k.shortcuts

You can sort your worksheet tabs with a macro, see SortALLsheets
SortAllSheets -- The following code will sort sheet tabs (#sortallsheets)
within "Build Table of Contents, similar listings, working with Hyperlinks"
http://www.mvps.org/dmcritchie/excel...#sortallsheets

You can also rightclick on the navigation arrows to the left of the worksheet tabs
to see a list of worksheet tabs if you have only a few, or on the "More sheets"
within that list to see them all -- it helps if you've sorted your worksheet tabs as
above, and you can use a macro to bring up the "more sheets" in a more direct fashion..

Just a suggestion.

When working with large multi-tab excel files, it would be nice to be able
to arrange tabs in a meaningful way - grouping or stacking or inserting
spacers. Also, tab shapes and fonts should be flexible.
