Hey there,
thanks very much for your work on the module! I've reflected some of these changes in
http://open.silverstripe.com/changeset/86151
http://open.silverstripe.com/changeset/86152
In general, your work will be much more "noticeable" if you post this stuff to our bugtracker, as documented on http://silverstripe.org/tag-field-module. Also, it is hard to determine the actual code changes if you submit the full module files, please use a patch format instead (see http://doc.silverstripe.com/doku.php?id=submitting-patches). Also, I've added unit tests for the deletion feature you added - have a look through them, we appreciate tests being submitted with patches.
Thanks again!
Ingo
