I Want a new type of custom field is to be introduced termed as Checkbox field to every custom field.
It will be by default shown as column.
Thanku @lubos for transferring this to ideas category for possible future implementation
Added to the latest version (22.8.17)
There is new screen for this type of custom fields
Works on top-level
And individual lines too
Right now, checked value will result in Yes and unchecked in nothing but I think I need to improve this so user can configure themselves desired text for true/false.
