Two suggestions:

1. Currently we can only set one set of rules. This should be changed OR it should have the option to select "OR", because all options are of the "AND" kind.

2. Allow us to manually configure how many topics will be archived per batch. I've read some older discussions and Matt Mecham, who wrote the code, is aware of that. Hardcoded to 250 at writer.php. Should at least give us an option to add the new value at conf_global.php. An ACP setting would be super.

I like the idea of (2) , I'd (personally) suggest it was a "power setting" though that went into conf_global, so it was treated as an advanced configuration switch for power users or those who required its adjustment.
