Apologies if this was requested already, but couldn't find any issues at this point, but here's the thing. the 'file/add' path is loaded by default in the frontend theme, 'admin/content/file/import' is backend theme which is a bit confusing sometimes. Is there a reason why this is decided like this ?
I'd be happy to write a patch to make the configurable - at bit like the checkbox at 'admin/appearance which says ' Use the administration theme when editing or creating content'. We could add
- a checkbox add admin/appearance, but that would involve a form_alter which is probably not that interesting
- or just a new settings tab at 'admin/content/file/settings' or 'admin/structure/file-types/settings'
Let me know which option you guys prefer - if wanted of course. It would save me hook_admin_paths() in all of our projects :)
