Hello,
First of all, nice plugin!
I'm trying out the Fleekdash demo, and I have a question about how to disable Fleekdash's “column manager” and use great "Admin Columns Pro" plugin instead.
PS: Keep in mind that many of us are just looking for a more modern interface for WP admin, but that's it. To performance, manage columns, advanced searches in the backend, etc., we already use specialized plugins for each of these things...
