Hi Rob,
Sorry that I missed your earlier mail through contact form. This usually happens when you don’t input the license key, so it won’t go to the priority list and will be eventually answered as part of the free support.
1. Right now exclusion is disabled only for the Administrator role. I’ll add this as a to do list item. But this sound more of a training issue and can be avoided.
2. A default permission structure is already in my to do list item. Its not possible with the current UI, but you can edit multiple posts/pages together using bulk edit.
3. As far as I know, this is part of the WordPress default permission check and has nothing to do with my plugin. Can you re-verify your user permissions?
4/5. Sorry, not possible at this moment through UI. But I might be able to give you a code which you can add to your functions.php. Right now where does the user get redirected to?
Thanks
Syam
