#1410 ability of adding new tags in the SystemClass of a SWF
Date created:
Type: feature
Visibility: Everybody
Assigned to:
State: new Help

As far as I know, it's possible to add new animations in Sprites and new sounds in Sounds, but they are becoming useless if they cannot be named. And there comes the SystemClass tags that show exactly the names of these.
