They won't show folder content because that sort of thing is handled by Windows itself and does not appear to be a live overlay, so Windows generates the whole image on the fly (folder, tiny content and all). As far as I know "that's just the way it is".
As to the icon size - well, you see, back on the school playground Nikos and I had a scam we used to play on the other kids: he was known as Nikos the Chince from his habit of teaching other children how to play poker with questionable rules, and he would take all their milk-money away from them.
Afterwards, I (who was known as Kilmatead the Kind) would let them win half of it back just so they didn't feel short-changed and run home to mummy complaining about us, and Nikos and I just split the profits without ever being ratted-out.
Now, though, 35 years later, it turns out that I was actually the cheap one because when I originally made this utility I just took whatever silly icons I could find - which had a top-size of 48x48 - but newer versions of Windows are happy enough to extract stuff like 128 and 256 and use them to "fill the space" properly.
Ironically, if you look through the "default" icon collection I provided in the download, other icons like the Camera.ico found under "Miscellany" actually do provide the larger sizes, and so will expand accordingly.
My basic idea was just to give people an idea as to what they could use and leave it up to them to source an icon collection they might find useful and more to their taste. I just use details view all the time so never saw a need for anything above 16x16, conservative old-timer that I am.
There's a user around here called
Kunkel321 who is sort of a self-styled Icon-King and may be able to find something more suitable if he's paying attention and is interested in helping out for a change.

(Feel free to send him lots of PM's about it, just so he gets a taste of his own medicine.

He may or may not demand half your milk-money, but I doubt it - he seems like a decent chap.)

Not without writing a whole other utility (which would seem a bit overkill), or (in extremis) replacing the default icon-image in Windows itself, which you don't really want to do for all sorts of reasons.

It wouldn't make much sense either, as ten folders in same directory could have 10 different icons on them - which to choose for the new folder? Hence, leave it up to the poor bedraggled user himself.
