It depends on how complicated this eventually gets, I’m currently working on 4 more other bugfixes/changes as well, once those are okay, I move to this one. The next release deadline is tomorrow (+ the approval time by codecanyon, usually within 48 hours). The index table already is capable of indexing attachments as well as most of the attachment fields, so if nothing goes wrong, this will be a minor touchup only. There is a chance I will be able to get this done by the upcoming release.
