Problem
When working in Jira, a project avatar is one common way that admins will customize to help users quickly sort through to identify what project they are working in. When you then have to switch applications to Confluence or alike, there is no means to automatically use the same custom avatar icon for that linked space. This can cause confusion or delays until users can be sure they are working in the correct space/project
Suggested Solution
It would be awesome if when you link a Jira Project to a Confluence space, if Jira would prompt you to sync the avatar between these two. Granted, it would be understood that the user creating this link would need to have admin rights in both applications likely, and there might be a question of which avatar to use when initiating the sync. However to be able to do this automatically for admins would be really helpful in making it very clear to end users which content is linked to what other content.
Note:
This suggestion does not seek to sync avatars of user objects. Just that between spaces and projects.
