File systems

We don't really need them. I should only have to decide where to put my files once in their lifetime, and not be forced to remember where the heck I placed them every time I need them

cdargs and fuzzyfinder help a bit here. I need that for documents in general. An indexing tool might do it just fine.

Browsers

A browser with the looks of konqueror with the link-navigation-with-keyboard (shift+arrows) capability of opera.

Session: a group of browser windows and several groups of tabs (one per each window)

I'd love a browser that allows me to handle several sessions, save them, load them, use them concurrently. The vim session handling is a perfect model for that
