Hi Tim, thanks for your kind words.
The place to specify the grey background is /theme/your-themes/config.php. Just add:
$THEME
->autolink = "#EEEEEE"; // To color auto-generated links (eg glossary)...and rollback your changes in style.php
Glad to know that automatic links works in multi-byte languages! thanks!
The default values for the settings is temporal... I'm planing to change it and allow admins to specify them in the admin modules page.
To make the hack of the ALT tags.. just change dynalink.php. It should be easy... but remember that you will have to do so everytime you upgrade the glossary...
Oh, by the way, comments could be far more useful than a way to express their graitute.. You could use it as a way of co-evaluation of user entries (everyone talk about other's entries)... which is a very interesting use, I think.
And last but but least... The feature you are requesting, a printer-friendly version of the glossary, seems to be useful... Please, file a bug in moodle.org/bugs in order to have an eye on it in the future.
All the best, Tim Williams...
Will
