- tweaked threading algorithm so that it sorts by subject first, then by "Message-ID:" and "References:" headers (much better)
- removed Subject/Date threading functionality
- removed block-processing functionality
- hacked threading code so thread summaries are generated completely before being made available to the user (gets rid of those "Thread file is out of date-- use anyway?" messages)
- switched to CodeWarrior as a development environment; this resulted in some bugs that will go away once I reconcile with 4-byte int's (I know I don't *have* to) and the latest Universal headers
- modified subscribed groups window so that it shows the number of unread and the total number of articles in a group (naturally, "total" means both read and unread articles)
- enhanced the code such that all references to deleted articles are removed from the threads database when/if the articles are deleted at quit
- optimized the code for reading in the threads database for currently available articles (i.e. ones currently stored in the news folder hierarchy)
- completely reworked the internal thread database code; cacheing is now done, and the interface to the thread database has been restructured so as to make it easier to finally get the NNTP stuff to work, and to remove the need for an external unbatcher/expirer like ToadNews (sorry John!)
- read the Thread Manager docs窶 maybe I'll actually use it (note that the Thread Manager is related to something very different from the threads discussed in relation to Usenet articles :-)
- ripped out the mail support since I don't have time to support it anymore (get Eudora or FernMail!)
- got NNTP sucking working, now on to posting and getting group names.....
- fiddled with the functionality of the arrow keys; now a left arrow marks an article as read and advances the article selection, and a right arrow marks an article as unread and backs up the article selection
- rewrote most of the file-access code and removed all support for pre-System 7.x calls
