At this moment there are no plans to support the Event Manager. There are simply too much plugins that we can support with our product. We have focused on making our plugin as compatible as possible. For most plugins you can create columns with with ‘Custom Field’ type. See more information here ( https://www.admincolumns.com/documentation/columns/custom-field-column/ )
I did take a quick look at the Events Manager and the problem here is that is uses not really the ‘WordPress’ way to add their own columns to the overview. Therefor their columns are not shown in our default columns list when editing the event post type. This means that if you save your custom settings, the field ‘location’ from the Events Manager is removed. You can alway restore the settings for that post type, but it’s not possible to change this overview by missing some of the plugins features.
