Please allow us to change the default sort for Open, Resolved, .... issues under the Project Summary on the right hand side of the Browse Project page. Currently it sorts by issue key which is lame. If you can't make this variable then please just sort by priority which is done in many other places. Thanks.

What I did:

the file I modified to get sorting by priority descending was

jira/includes/panels/browser/openissues.jsp
