Hi Sergey,
Your plugin already adds the "Tag slug" field to the custom taxonomy oage, but it doesn't save.
Since custom taxonomies basically use the Tags interface, it should be quite easy to extend support to edit custom taxonomy slugs as well.
Thanks for reading!

Saw in the new version that you added support for custom taxonomies!
That was fast! Thanks Sergey! :)
You're welcome :) I replied to your e-mail yesterday, but the domain name seems to not exist at the moment.
is this plugin still needed since the merge of wp and wpmu?
Editing term slugs is unavailable if global terms are enabled. This feature is disabled when installing WordPress 3.0 from scratch, but is enabled when upgrading from WordPress MU.
This plugin is only needed if you can't edit tag slugs on your install. Alternatively, you can disable global terms by changing global_terms_enabled key value to zero in wp_sitemeta table via phpMyAdmin.
