Big things come in small packages, as they say, and this particular feature added in OnePager 6.1 fits that description perfectly.
In 6.1 a new checkbox was added to the Comment Boxes tab on the Project View Properties form, per the below image, that allows a user to make the comment box transparent, and draw a line between the task/milestone shape and the comment box itself.
The transparent box gives the appearance of a floating label, and the new line allows us to visually connect the text to the corresponding shape.
The example I created above was generated by using task absorption. However, you may also turn all of your task or milestone labels into comment boxes using the Task Bar/Milestone Label Properties button, per the below example.
There are likely many ways this small enhancement might be utilized, and we look forward to seeing what you come up with!
