As many Marketplace partners work to transition their Confluence apps from Connect to Forge, several UX-related limitations in Forge have emerged that significantly impact migration feasibility.

One notable issue is the restricted width of byline dialogs when using Forge’s custom UI with adaptive height. Currently, this dialog width is fixed at 288px, which severely limits the amount and layout of content that can be meaningfully displayed.

In Connect, byline dialogs can be rendered at significantly wider dimensions (e.g., 500px or more), enabling applications to present rich, interactive, and user-relevant content without compromising usability.

This dialog is often a central interaction point in apps built on Confluence, and the fixed narrow width in Forge presents the following challenges:

• Forces unnecessary redesign of existing user experiences

• Reduces usability and visual clarity of UI components

• Requires substantial effort across UX design, development, and QA

• Risks delivering a suboptimal or degraded experience to users post-migration

Suggestion:

Introduce support for wider or configurable dialog widths in Forge (particularly for byline entries using customUI with adaptiveHeight). Ideally, this could include either:

• A larger default width for byline dialogs, or

• A configurable width option (within reasonable bounds) for app developers

Benefits:

• Eases the transition from Connect to Forge without requiring full UX overhauls

• Preserves usability for apps that depend heavily on dialog-based interactions

• Enables more flexible and rich user experiences within the byline context

• Reduces migration friction for vendors aligning with Atlassian’s platform direction
