I used this mod since 2006 (when i started with zencart) and alway accepted its quirks because there has been many other mathers in the shop that needed attention first.
It has always been low priority to me because it worked more or less.
Alway made a smal fix (patch) for one problem at a time and neve came to a complute solution.
With the security taken to a much higher level i am facing similar problems in other mods i was developing and now it has high priority.

Because this mod has everything i need further on in my mod development i will rewrite this one first.

What i did until now:
Made the mod language aware.
Made the mod currency aware. (no more fixed $ signs)
Removed the fixed tax settings and follow the shops tax rules.
Changed some fields from text input to dropdown.
And last but not least confirmation to the security framework. (worked on at the moment, almost finished)

Some other mods i am using included in this one but still need some fine tuning for those not using this other mods.

After finishing up i will upload to the mods but since v2 is occupied i wonder how i should name this new version. (V3 ?)
