I recently switched from sh404SEF to AceSEF, and overall I am very happy about that decision. There are a couple of things about sh404SEF that I like a lot better, however. Their 404 Error Page is much more sophisticated. The specific features I really like are that it embeds the specific URL that caused the 404 error and it also recommends a list of similar pages for the visitor's consideration.

Check out the following URL for an example of these features:
www.spease.com/articles

I hope you will address these issues in a future (and soon-to-be-released) version of AceSEF.

Welcome Matt.

We have this on our to do list for a long time and I hope that our devs will include it in the next version.

Hi,

it would be great to use a Zoo Page for 404 Site. I don´t use com_content and have it disabled.

best regards,
Markus
