Wagn is the excellently intertwingly software running this site. I've on and off been working on it with Ethan F McCutchen, Gerry Gleason, and Lewis Hoffman for over six years, because it scratches a lot of itches I have for certain kinds of capabilities that other software does not offer.

import - interpret lists in a field as items in a Pointer
Show a different thing in a card — and/or a different order in Pointers/Searches — based on day of week (eg for GTD) - doable via Ruby, as is random, for a demo of which close and open this:)
Ruby cards are being deprecated. Something like "sort":"random()" in WQL should do this.
Two-way sync with a Wagn on my laptop - downloading all pages as text files would be ok for starters - .txt is done (what's it look like for formatted cards?), just need a bulk mechanism

test.txt - can do hrefs by hand
If a page is public in a personal wiki, the background color behind the text could be noticeably different, or some other means to http://wagn.org/wagn/make_permissions_visible_in_View_tab
http://www.wagn.org/wagn/organizing - drag & drop Pointer order, etc.
Some way to bulk change permissions (e.g., set all cards specified by a given Search to be viewable by Anyone Signed in.) - See http://wagn.org/wagn/operations_on_groups_of_cards - not searches, but any set when we setting-ize permissions, although +*self will override.

√I want to be able to create cards for people, then invite them. If (and i'm not sure) i want those cards to then become their User cards, that requires a change (right now you can't invite someone under the name of an existing card).
Workaround was to make InvitationRequest+*tform, log out and make InvitationRequests for each such person, then only invite them when i want to.
