I didn't post any status updates for long time so this will cover three topics.

1. Usability issues

I have fixed 43,46,52,53,54.

The most visible result is a new pagination, screenshot in attachment.

2. Garbage collection

Basically it shows unused images and thumbnails and allow user do delete them.

You can preview demo here:

This is my first work with sapphire core so I would appreciate any code review, everything is in r40463.

3.Article

I will be writing a SilverStripe tutorial for http://www.phpsolmag.org/. Currently I have written plan and summary and I'm waiting for feedback from publisher.
