For those who may be interested, I have gone ahead and pushed Pierogi 0.6.1 up into the extras-devel repository. This update includes:

• Moved the Mute button to the main tab, shuffled some buttons around on the Utility tab
• Made a first pass at keysets for Admiral, Daewoo, Grundig*, Logitech, Philco, Roku, and Topfield

This version may be a bit more unstable than most, as I've thrown together a lot of code in a fairly short time. Be warned!

*BTW, wow, Grundig is tough. There were at least a half-dozen different IR protocols in just the config files available from the LIRC, including a few I've never seen before. I probably only managed to encode a third of the files into Pierogi; odds are good that it'll be a while before I can provide decent coverage for most Grundig devices...
