Hi tarkhorani,
1. See
http://pkp.sfu.ca/support/forum/viewtopic.php?p=6685; we probably won't distribute this modification with OJS unless we get a lot of requests for it, as I don't think it would be a widely-used feature, but we may add options to the email system in general that will allow additional addressing.
2. Payment support will be added to the next release, which will be OJS 2.2.
3. Do you mean searching or sorting? There's a discussion of sorting options at
http://pkp.sfu.ca/support/forum/viewtopic.php?t=2017; as noted there, we'll be adding clickable table headings in a future release.
4. This feature is already planned; see
http://pkp.sfu.ca/bugzilla/show_bug.cgi?id=1709.
5. The CMS plugin, which is already in CVS and will be released with OJS 2.2, should serve this purpose.
Regards,
Alec Smecher
