What tools or window managers do you like to try and review?

I would like to test mblaze, a set of utilities for handling mail. I'm still looking for scripts based on mblaze.
Other tools I'd like to try, but I have no idea of any, are unixy organizing/todo/pim tools. Nothing monolithic as emacs orgmode, but something like mblaze: a set of tools. Do you have any idea of a set of tools for self organization and scheduling?.

For the wms, there are some non-conventional wms out there: wmii (which I have never tried, but like its features), z3bra's glazier, and I also just wrote a wm: shod. ctwm is also a wm I'd like to test.

I can open a thread for those try-and-review activities and get in charge of them.
