In the late 1990s I was working through organizing some of my writing and rearranging the order was done in the bookmarks editor of netscape on an SGI O2... About the only decent modern equivalent seems like Omnioutliner. (org-mode?, eek). It would be swell if the slew of paper with (gradient descent combine)-named sections and subsections would stop, or at least be mollified in some way: being able to have more fine grained control of sectioning and subsection, preferable through a gui, might have some damping effect.
