I confirm that the remaining (known) bugs have been corrected, and that I have succesfully used the script on my products

Thank you again Fred and snibgo for helping me out on this!

Have a nice day,

I updated the script so that now it works also with non-square AR + it always keeps the AR in the zero padding case. Details about the script at https://github.com/coccoinomane/trim-ratio, latest zip here => https://github.com/coccoinomane/trim-ratio/archive/v1.1.zip There still is a bug whereby non ...
