Allow downloading attachments directly from a wiki page

[ben@…]

Currently, downloading an attachment from the wiki requires two steps:

• Click the attachment link at the bottom of a wiki page
• Click the download link on the attachment page

This is annoying in two cases:

• When trying to download multiple attachments from the same page, this forces the user to keep going back and forth between a wiki page and its attachments' pages
• When trying to download an attachment that can't be previewed (because its type doesn't have a renderer or because the attachment is too large), this forces the user to go through an extra page

I propose that the attachment list be changed so that it allows direct downloading of all attachments, and viewing only of attachments that can be viewed. Something like this, perhaps:

Enormous.jpg (1 GB) - added by ben 1 minute ago	Download
System.iso (3 GB) - added by ben 1 minute ago	Download
Small.jpg (1 KB) - added by ben 1 minute ago	Download

To avoid having to sniff the MIME type of every attachment on a page to display the page, attachments' MIME types would need to be cached in the database.

This would be nice!
