1. Folders in the Shared Files module look like it should be possible to add a description (there's a description column when "Show Description?" is switched on for the feature). But when I go to Edit Folder, there's a big gap above the Parent Folder and Folder Name properties, but no HTML editor. Should there be?
2. The "Uploaded By" column in the table gets some rogue leading spaces, e.g.<td>&nbsp;&nbsp;&nbsp;Joe Bloggs</td>

Ah OK - it was the large gap on the editing page made me wonder if something had fallen off by accident.

I'd seen your guidance about the use of the description field for indexing, and actually I'd like to have both, a visible description plus a hidden one for indexing content (can that find its way onto your list of requests - low priority).  But this makes me think... the files could perhaps be loaded into the database and indexed there. But perhaps that would be a SQL-Server-only solution that would not work in the other mojoportal database platforms?

Yes that was exactly what I meant - a brief visible description such as "Original user manual for the X55 discombobulator, dating from 1955", and a place to put indexable but non displaying text (such as the content of the PDF/doc).  So yes I guess hiding this indexable text with css would work - nice tip.
