(OFF) Dear developers et al.! Thank you very much for your wonderful system!
It would be a nice feature if I could sort list of all the issues (e.g. /view_all_bug_page.php) by two columns.
(e.g. in my special case I needed ORDER BY STATUS, PRIORITY)
I can implement this by adding an extra line to the filter display. This would set the sort order with two options from the visible list of fields. The existing sort UI (clicking on the column title) would revert it to a single field sort.
