Allow administrator to limit filtering to certain content types

second that, with multiple-select to choose more than one type to display

Hmmm, a bit too quick comment above, did not see anything in the interface right away, but then I spotted the following info which I am trying to figure out how works:

"- Ability to display terms from a certain category as tabs, then users
can restrict the listing to the one term in the category

- Ability to display content types as tabs, then users can restrict the
listing to the one content type (blog, image, page, ...etc.)"

Where is this done?
- How to get the content types as tabs?
- How to select only some categories (=terms...?) or levels from a vocabulary so not all terms from it is shown? Or is not that the idea? I think that the above sentence perhaps is not promising that, and if it is not, it could instead be rephrased into something more specific, like:

"- Ability to display terms from a certain vocabulary as tabs, then users can filter posts to terms from that vocabulary"

I set this as a support request instead, and filing a new feature request regarding the multiple-select.

oops, what happened, didnt I close the blockquote properly, ommiting the slash, perhaps? Ended up with a nested new blockquote instead of closing the one I wanted. Oh well. The last one is my comments and not a quote. (blockquote in my previous comment corrected)

Ability to display content types as tabs, then users can restrict the
listing to the one content type (blog, image, page, ...etc.)

It's this possible??? I just want to display some of my content types... and I don't want to hack the queries or something, as I imagine most of people will also want to hide some content type from there...

Simple but nice module.
Looking forward to be able to do that...

hm, this must be a feature request, as features are not in place?

Well... I copy&pasted that sentence... from your post!
Uhm... yep, then it's a feature request...
Do you know if this module is still in development / maintained ? I wish it is...

It is maintained as long as people need it AND are willing to contributed patches for the features they need.

Hi,
I think it's quite easy to understand what I want. Instead of having a tab for each content type, give the option to just select the content types you want to display in the xtracker page. That way, one can have content types without use, and the users don't get another tab for nothing (most of the time, with no nodes inside..).

Anyone has an idea on how to do that?
Thanks!

Yep, and I was trying to use the patch or even the xtracker.module file posted in here http://drupal.org/node/36836
But it's an old version, and doesn't work at all. I wish I could adapt the old patch, but I don't think I'm capable to do that..
So, I think there's no option (yet) to do it in Drupal 5.
