Ability to configure Core board to show issues for more than 14 days and remove issues before 14 days

Problem Definition

Case 1:
For leading tracking (a use case specifically support by JIRA), having
items on the board for more than 14 days is extremely common. In some
cases, this can easily be up to 6 months.

Case 2:
A customer has too many issues in his "Done" column and wants to remove them before the 14 days term

Case 3:
A customer has multiple columns tied to statuses that are configured to Done category.

Suggested Solution

Make it possible to configure a Core board to show issues for more than 14 days.
Make it possible to remove issues from a Core board before the 14 days term.

Workaround

This is by no means a fix but I hope it will help you get quicker access to those Done issues that are more than 2 weeks old:

1. Write a query that returns all issues in a project that have been done for more than 14 days e.g. 

   project = CJSWK AND (fixVersion in unreleasedVersions() OR fixVersion is EMPTY) AND status = Done AND NOT (updated >= -2w OR statusCategory != Done) ORDER BY Rank ASC

1. Run that JQL and copy the URL of the search page
2. Create a shortcut that links to that URL. I called mine Older Done Issues:
