Hi guys,
Nice plugin, been using it for a few weeks and am very happy with it.
I've come across an issue with the way your Preview & Select Columns links are created. It has been raised before but I don't believe the fix is the correct solution.
I and many others always install WP in a sub-folder (e.g. /wp) for some added security, but since your plugin uses 'site_url()' to build it's Preview and Select Column links, these are not going to the correct 'live' URL. The hack fix (which many do not like to do) would be to stick a copy of index.php & htaccess into the sub-folder as-well but that isn't very elegant (to me anyway).
Using 'home_url()' instead would be a safer function to use to cater for all setup types.
Right now, because I have a blank index.php in my /wp folder because I do not want 2 entry points, the Preview & Select Columns link only ever return a blank screen.
Maybe we're the minority, but could you think about changing it?
I don't believe there are any performance issues related to the change.
Thanks.
