Created attachment 6340 [details, diff] remember patch for 0.1.14
Dang! You beat me to it :) BTW, I have come to love the vano-patch [/usr/portage/x11-wm/fluxbox/files/fluxbox-vano-gentoo.patch] that allows you to left click anywhere to make the menu vanish. It might be nice to those that are used to it. I tested it and it does work with this new release.
If you haven't noticed already, 0.1.14 is in the tree. The vano patch and menukey patch are applied. The remember patch line is in the ebuild, but it is commented out. Edit the ebuild and uncomment that line (easy to spot) to get the remember patch.
