I must really apologise - yes, it works perfect! I was confused by the missing description of this feature on the ScreenShot page and I did not install your plugin at first. That was a big mistake.
This is really a BIG improvement for structuring media files much better.
Unfortunately, WordPress is very poor in selecting some of these files WHILE EDITING a page (Insert/Upload image icon). There is no sorting of files by Name, Date, ASC, DESC - just searching for some (sub)strings in the file names (and the months). WP3.2.1 has made no progress(!) as regards and there probably is no plugin solving it.
Ulfben, do you think it would be possible to add something like this into your plugin in the future? It would probably be quite sufficient to have a combo-box "select uploads subdirectory for media files search".
The full implementation of sorting (as mentioned above) would really be an incredible step forward, worth adding to the WP core. I can imagine it would be a lot of work, though.
Nevertheless, thank you very much for this version of the plugin.
With best regards, Joo
