Can the duplicated fields for mock up and attach files be removed from Projects/Action Items (Features) Layout?
Thank you for your idea!
When creating custom fields, the custom field type Note includes the mockup and attach files options as a way to provide a visual aid. It also includes the text editor, which gives you more formatting options. However, if those are not desired, one suggestion would be to use a different custom field type such as Text.
At this time we do not have plans to update the note custom field type. We hope you can understand.
