Key genre tempo progression filters

Hi, love Chordify.  It would be great if we could filter searches by key (I just want to play G progressions today to match my C harmonica.. or open-tuned G instrument), Genre (just blues, please), tempo (hey, I'm struggling when I go over 90BPM... let's keep it slower.. or i'm just in the mood for faster/slower), maybe even progressions (just want to turn-off brain and stick with 1-4-5).  We could really discover a lot of new/attractive content if we could effectively search by keys/topics like those.. vs a specific song/artest/website.  Ponder/cheers!
