How to add issues and comments directly on the Agile board
First of all, you have to enable these features. To do it, go to Administration -> Agile, and check Card creation and Inline comment. Don't forget to click save!
When you are in Agile board view, you will see a light gray dotted border with Add new issue - just click on it and start describing the issue you want to add.
Please note: when creating the issue onboard, you provide only its name. To add more details, edit it.
To add a comment, hover on the bottom right corner of the issue and you will see the comment icon. When you click on it, there will be a text input available for you to provide a comment. Click Submit when you're ready.
Please note: all comments are being saved to the issue history, however on the Agile board you will see only the last one.
Important: these features will work only if there are no swimlanes on board.
