[Plugin: WP-Filebase Download Manager] Sync filebase batch

This plug-in is really useful and easy for end users. I have encounter a problem as many other users in the support pages.
When the file database gets large either the PHP memory limit or the max execution time prevent a sync of the filebase.

As many end users have shared hosting it would be really useful if you could either specify a batch size or a category to sync.
Is there anyone who have made any progress in this direction?

Maybe we could work on the following function line 19 in Sync.php

private static function PreSync($sync_data)
{
	@ini_set('max_execution_time', '0');
	@set_time_limit(0);
}
