Disable the Kanban Backlog messages and pop-up

Problem Definition

JIRA 7.4 introduces Kanban backlog. With this feature, if a column has more than 20 issues, JIRA will show a pop-up asking user to enable Kanban Backlog:

This pop-up can be dismissed but upon re-login and opening the Kanban board, the same pop-up will be displayed again.

Moreover when all issue status from the Kanban backlog column are moved to other columns, then the epics panel is disabled and a message pops up on the top right of the screen Help us improve the Kanban backlog:

This is annoying also because it give to users the possibility to reach out to third party (in this case Atlassian and some Jira admin may want to disable this possibility for users.

Suggested Solution

Allow user to permanently dismiss the backlog pop-up

Workaround

None
