Since Tugboats have a TC-like authentication, any chance that Tugboats could be added to this plugin?

I'll look for it, yes.

Came to say the same thing, would be great as an addition 

Hi,

The way they works is totally different, there is no way to detect authentication of Tugboat without looking constantly ALL of them (because there is no related event), so it's too time consuming to do so.
It's not a "no", but a "later"
