I think a possibility to show fullscreen Custom UIs (adminPages, jiraProjectPages or at least a fullscreen modal) is urgently needed. Confluence offers this for Atlassian Connect and Forge Custom UI. Currently Jira Custom UI does not offer a single possibility to show larger configuration pages for complex add-ons or a fullscreen page for like project-summaries.
My guess is that adminPage and projectPage (both available in Connect) are the key features that will prevent many Connect apps from migrating to Forge:
- Simply from a UI perspective the available Forge modules are just to small. Missing space for complex configurations.
- All available Custom UI modules in Jira are just “issue-scoped” (IssueGlance, IssuePanel, IssueAction…) – no possibility to allow project-summary-like features.
- The available Custom UI modules are visible for everyone. No admin-pages. No conditions (whether to show a menu item).
Given that Forge Custom UI is the future for AMP apps, I think these are the key roadblocks for many vendors. The most popular marketplace apps rely on the mentioned Connect-modules which are currently missing a Forge-alternative.
