As no bug reports have been posted here, I have decided to upload v2.0 to the zen-cart.com downloads section at:
http://www.zen-cart.com/index.php?ma...roducts_id=101 (and attachements to previous posts will be removed)

#####################

Some ideas for future releases are:

Add feature for cross sell updates
Add "quick column on/off switches" (quickly disable unused columns to speed up the script without having to change the admin settings)
Markup by purchase price (currently markup is done by price only)
Add default markup value
Improve margin calculation updates (currently the shown margin is not always up to date)

(no idea if or when the above will be added though, and feel free to add it yourself of course ;-) ;-) )
