just randomly inserting my latest version of wishlist:

-even faster tires, kojaks next
-swap out longer klickfix mount for klickfix caddy
-try a bunch of fits for saddle angle, fore/aft and for handlebar height, handlebar style (moustache, some other versions of upright)
-swap out for titanium seat post
-swap alfine 8 for a 3 speed hub (probably 40", ~53", ~71"). probably sram i-motion 3 speed. i'll miss my higher gears, but i'll be fine without them. - my only hesitation here is that if a 3 speed hub is having issues with 1 gear, it makes the bike unusable.
-find mount locations and mounts for tail lights
-some way to mount front bag against frame/headtube
-some simple mechanism where the folded pedal could connect with the handlebar, to keep them locked together when folded
-a very lightweight 2 foot kickstand, for holding by steady when attaching panniers/bags
-wheels locked together quickly when folded, so front wheel didn't sway (i use velcro strap now)
-belt drive
-coaster brakes in rear
-a permanently attached fender that didn't get worked loose by seatpost
-igh with the easiest detachment mechanism for fast flat tire changes (i believe i-motions)
-18 inch wheels, save a little more space..
