The Roadmap Planner is a great addition to Confluence, but lacks the ability to be resized or resize itself automatically based on content.

Vertically, the lane labels are very short and cannot display something as simple as the word "General" without being cut off (with 2 lanes).

Horizontally, the bar text does not auto-shrink if the bar is too short to display the label.

Additionally, the editor view does not give you an accurate representation of what it will look like when you save the page. There are 3 stages of how you will see the content, and they all are inconsistent (see attached screenshots)

1-In the actual macro editor
2-Once you click Insert on the macro editor, but before the page saved
3-Once you click Save and view the page as normal

I would suggest allowing the ability for this to be resized manually or have the label text auto-shrink to the size of the fields.
