Thats ok, I don't get emails either sometimes from here either
Maybe the html isn't in the previous version, I was looking at V4 files for 1.3.8. and I think I added new stuff in for it.

The product listing file is the one I always find myself modding, maybe future zc versions will split out some of the processes into separate files, so the product listing display itself, is easier to understand and modify.

My reading of zencart is, it maintains its status partly by having excellent back end admin.. ideal for selling with..

The add-ons for zc are not as straightforward as some with other open source, zc could do with an easy module install/uninstall system, - but zc has other amazing attributes instead. Without an instant install/uninstall it means 3rd party add-on-makers have probs in charging for add-ons, cos using zc add ons is clunky. Its not a 1:1 comparison in any way, but I use joomla a lot and there are masses of little add on suppliers who offer cheap (and not so cheap) modules.

On the other hand, I think there's a background tradition here, that zc add-ons should remain free if possible..
