download files page defaults to edit mode

[Martin Pool]

The download files page https://edge.launchpad.net/bzr/+download defaults to 'edit mode' -- if you have permission to modify files for this project, then it's full of 'add file' / 'delete file' controls. Now that bug 145416 is fixed, this appears for many more people.

Generally Launchpad displays objects in a 'view mode' first, then you click an edit action to make it editable. So this is a bit inconsistent which caused John some confusion about what is happening on this page.

It also means that for people who don't have permission to edit this, they never get a message, they just don't see the controls.
