Old G2 modules for G3!

Hi

I was wondering if anyone knows if the checkout module available for G2 was likely to be made available in G3. I'm missing the extra options, like downloading purchases.

While on the subject the G2 thumbnail module was much more useful, for me at least, allowing different watermarks per album and watermarks on the full size image.

I'm just a user who is muddling through the upgrade, so wouldn't have clue what is involved – but if anyone knows if these are being worked on (or would like to start!) I’d be grateful.

Thanks
