action:categories.loaded only on infite scroll

[rbeer]

Hi!

I want to alter the category listings, namely the links to each topic.
There I noticed that action:categories.loaded|loading both trigger on scrolling, only. Neither on the initial visit (when loading the first X topics) nor when pagination is used.

I am about to use an ajaxify hook and check for the url; just want to make sure that there's no other, maybe better way to do this, is there?
I wouldn't need any data, just to know the fact, that the user is in a category/topic listing.

edit:
Uhm; noones signature is showing in posts. Did I miss that before?

Thanks
