The Configure your Issue Navigator option on every filter takes a very long time to open the screen the first time any user hits the page per user session. reproduce: So user a tries to configure their issue navigator. System spends 5+ minutes opening screen. User configures their issue navigator and goes back to filter. User then manages filters and adds a column order. Issue Navigator column config screen appears instantly. User then logs out. User logs back in, views same filter, clicks 'Configure your Issue Navigator' and has same 5+ minute wait. ... <b>I believe that the problem is that the default behavior for the 'Configure your Issue Navigator' is to first select on all issues in the system, then to present the user with the last 5 issues or so of the select on the configure screen. </b> It would be very nice if this default behavior were changed, if this is infact the problem.
