>Personally, I would not sub categorize my property sheets if it were optional, I like going, "cDataDir, thats easy to find...". Maybe I'm just used to it.

Yes, I'm used to prefixing (prefacing) the property or method too. But do you want all your properties grouped together only alphabetically? Maybe, but why not either/or? In the following I know the example is ridiculous but you get the idea.

            -BabyDir
cBabyDir    cBabyDir
cMamaDir    lBabyDir
cPapaDir    nBabyDir
lBabyDir
lMamaDir    -MamaDir
lPapaDir    cMamaDir
nBabyDir    lMamaDir
nMamaDir    nMamaDir
nPapaDir
            -PapaDir
            cPapaDir
            lPapaProp
            nPapaProp

I like the idea of having a choice of the 2.
