We recently rolled out a change to the developer platform which I neglected to tell you about. You now have more control over details displayed in the ticket tracker list view. This issue was tracked in [#4790] if you want to read some of the backstory.
As an end-user, you can modify the columns that are displayed by clicking on the tools icon at the top right of the ticket list. See https://sourceforge.net/p/allura/tickets/ for example:
This will bring up a dialog where you can select what columns you want to see displayed:
As the project admin, you can make this setting apply for all users of your ticket tracker in the Admin->Tools interface. Click on ‘Field Management’. At the bottom of that page, you’ll see a list of available columns, which you can turn on or off.
You can see what future changes are on the way by perusing the milestones in the platform ticket tracker, and you can influence this by voting on tickets.
