Hi Martin,
Thank you for looking into this, but I must agree with Carmen. I have not used any other plugins that come close to working with this group of settings, and my problems started immediately after I installed your plugin. Some specific examples that I’ve noticed:
1) In my dashboard I have a few modules enabled. I tried to change the location of a module, and it reverts to the layout that was saved with your plugin when I navigate away and return.
2) When I saved settings using your plugin, my sidebar menu was in the collapsed state. Now, none of the users on my system can keep this menu expanded for more than two page reloads.
There are other areas, such as the post and page editors, where I am able to change screen options independently.
