Yes, Xenofex 2 and the AlienSkin EyeCandy 4000 that were released together still work well in Xara.

I went through a phase a few years ago, where I searched for FREE 8BF filters and downloaded them, but I really only wanted them because they were there. I used hardly any of them.

There were (and still are) hundreds of them that work very well within Xara. Redfield and Mehdi has a few really good ones. Also look at "Harry's Filters" ... a lot depends on what you want to achieve.
