Can you browse just whole groups without searching?

If so how please ?

This is with Unlimited SuperSearch Premium Search Service Access.

I am talking about all headers of any newsgroup.

Not just a limited amount of search results.

Never mind found a competitor product that does this

If I understand what you wanted, that's one of NL's normal options. On the Manager tab, subscribe to the newsgroups you're interested in. On the Articles tab, check the box next to the one(s) you want to see headers for. Right-click to select the number of headers or days to download in all groups. Or highlight a subset of the groups (click, shift-click, CTRL-click) then right-click to choose the headers or days for the selected groups. Sounds complicated but it's easy and obvious once you've done it.
