It would be nice to have this option. This option should not be limited to direct parent/child relationship. Also, multilevel relationships should be possible to filter. For example, filter all issues that are descendants of specified issue.

Proposition of this functionality can be implemented by extending issues table by extra field (eg named ancestors_and_me). This field should contain all issue_id's of all ancestors of current issue (for example 12345), delimited by delimiter(for example '#'), folowed by current issue id (12345).

If ancestors_and_me for example contains this value:
"0009876#0007654#0003456#0012345"
That means that issue with issue_id 0012345 has father with issue_id 0003456, grandfather with issue_id 0007654, and grandgrandfather with issue id 0009876.
Something like this:

0009876

0007654

0003456

0012345

In this way filtering by parent/child relation is matter of simple SQL LIKE query.
