Active Projects In Subprojects Listing Only

Is there a way to only show 'active' projects in the subproject listing? Currently, it shows closed projects in the subproject listing on parent projects overview pages, and for my needs -- this is a bit redundant and inefficient for us, and I do not want to 'delete' the project, as we intend to keep our closed projects available for future client proposals and reports.

I have been toiling away at heavily modifying ProjectPier for my particular businesses needs, and this is my current hurdle.

I will be releasing screenshots / info on my edits on this forum shortly!

Yes, this should be fairly easy. Fastest solution is to edit the selection in application/models/projects/Projects.class.php

Change 'conditions' => array('`parent_id` = ?', $this->getId()),
into 'conditions' => array('`parent_id` = ? AND `completed_on` = ?', $this->getId(), EMPTY_DATETIME),
in functions getSubprojects and getAllSubprojects.
