I was wondering if you could implement a way control the case transformation of URLs. While I understand that in the backend Unix are case insensitive, I would like the address bar to contain exactly what I expect.
Let me show you my case why I would need it. I have product display content type which has a following Pathauto pattern:
[path/to/product/taxonomy/term]/[product-sku]
While the taxonomy term part can be all in lowercase, I would like the SKU symbols to remain unchanged and appear in the original typed-in case to better convery a product symbol - technical symbols are usually better perceived as - for instance - LBL-A6-GSM-Ex3 - rather than: lbl-a6-gsm-ex3
Since I don't think there will be much hunger for such a feature from other people, I don't insist on an admin UI for that, but I would gladly welcome a modifier such as:
[path/to/product/taxonomy/term]/[product-sku:case-orig]
or whatever syntax you see appropriate and savvy.

Thank you.
