I had a number of good old threads from this board bookmarked so I could read them later and wrap my head around their ideas, but then I lost them all in a hard drive crash (strike two, Western Digital!). I also had a number of Japanese BBS's linked from this board bookmarked so I could take a look at their software's functionality and get some other ideas.
Anyway, these are all non-template suggestions:
I also have an early idea swimming around in my head about only bumping threads a few positions up, instead of to the top. Another idea is actively bumping threads down, either by a few positions or to the bottom. I'm not exactly sure yet what good it'd be for.
Also...
>* I'll add thread closing to Kareha, but I was thinking of setting the default behaviour to never permasage or close threads.
I think this is ideal for the time, until we have enough statistical data to derive thorough auto-permasage and auto-delete/archive algorithms. Just add the functionality for mods to manually set these statuses, but remove the "permasage at 1000" behavior.
The standalone thumbnailer project is a great idea too. As a suggestion, how about adding functionality to also read and thumbnail document files like TXT, PDF, and DOC?
