I have a large site and the export doesn't work and the preview only shows 10 pages with the permalinks instead of the live links.
2.3 seems to be heading in the wrong direction. 2.2 was much, much better. I have a large site and right now I can not use the plugin even if the preview worked since it only shows 10 pages/posts.
This was one of the most important plugins I had installed as I have a very large site and need to make large changes from time to time. I hope the next release is more in line with a more functional 2.2 than 2.3 because right now the direction this is headed excludes large wordpress sites and companies.
