Enhancement request for Bugzilla

[Regina Henschel]

Hi all,

I want to make an enhancement request for our Bugzilla, but where? 
Neither Bugzilla nor Redmine seem to have a suitable category.

This is my problem:
If I attach a pptx, docx, or xlsx file, the option 'auto-detect' in 
section 'Content Type' does not work. So I try option 'select from 
list', but that list has no items for the OOXML formats.

So my request is to make the 'auto-detect' able to detect OOXML formats 
or extend the list with these formats.

Kind regards,
Regina
