Template edits

[Eagle Creek]

Hey!

I have a little questions about making plugins. I know it's possible to edit/add an template using a plugin. But I'm wondering: is it also possible to add an new column in the "forumdisplay" template?
I want to know this because I want to add an extra field, called ‘status’, to the forumdisplay. Of course I can do this using a template-edit, but it’s more easy to use a plugin (when possible).

Thanks.

EDIT:
Owh wait I think I found out :-).

It's possible to use a hook in forumdisplay to cache forumdisplay, and within that cache I can replace HTML to add an extra column.
