Going back to what @olifre mentioned, foreman_column_view provided the ability to add a column based on any fact. The selectable columns feature doesn’t quite provide the same level of customization as it’s limited to a small number of pre-programmed facts, so although the functionality has been integrated into Foreman, it doesn’t have the capability that it did as a plugin.
Is there any way to add a custom column without having to dive into the inner workings of the code?
