Sorry I've been off due to repeated illness and this is not "my module" (the original developers disappeared quite sometime back).

The only issues with combining the modules are 1) the orders.php used as a basis for super orders dates back to about 2007 and so sometimes it doesn't work on later versions. 2) super_orders or edit_orders both use window.back() in their links to go backwards through results which can mean repeated clicks through to the wrong places. 3) bad totalling of discounts or order re-totalling.

I'd solved quite a few of the problems certainly 1 and 2, but 3 remained an issue. Until I sorted some of the other issues with my own modules (and got healthier) I'll not be looking at this module's totalling up problems. I agree it was quite easy to just put them up on the same zen-cart shop but over time they don't play nicely together and the totalling and re-totalling appears to move further from the desired or correct values.

Philip.
