Sorry for the delay in the Plasma 4.3 show-and-tell session. The last couple of days have been consumed by some (much needed) drama on the xdg freedesktop.org mailing list, cleaning out some more annoyances in Plasma (e.g. dropping the time the device notifier takes to initialize by ~85% as it was contributing to a massive slow down on startup; apps are starting to install hotplug activation entries, and the algorithm in the hotplug dataegine, which hadn't been touched since 4.0 it seems, was not ready for it) and our semi-annual "planning the next release cycle" Plasma meeting (though that's always big brush-stroke stuff; the usual flood of fixes, features and new plugins is something we just take for granted ;).
So instead of having a nice calm second half of the week, I've had a silly-busy one. No rest for the wicked, right? :) Anyways, I will be getting that Plasma show-and-tell out this weekend. It will be a screencast. I have already written out the talking points script for it.
