The usability of shared dashboards seriously impaired by the existing 4.x dashboard list layout. People in my company just cannot afford using shared dashboards in Jira 4 because favourite list eats up 20% of full screen (even if you don't try to use sensible dashboard names and only have two dashboards in your "favourite" list).
Very wasteful, very annoying.
Please make favourite list either drop-down menu or horizontal (like it was in 3.12 plugin) or configurable if anyone likes the current layout.
