Following hot on the heels of Pushy, I’ve implemented the companion application Archivey. This will delete all but the last five messages on a wave, excepting the top message. It’s meant to be used in conjunction with Pushy and any other chatty robots to keep the number of messages in a wave down to a manageable level.
Potential other uses would be in a chatting context: you don’t always want to see the complete history of a chat session and this could be a way to hide the noise. Remember that you can always see the complete history by clicking Playback on the wave, so the messages aren’t lost: they’re just archived.
To use, add email@example.com to a wave. Be warned, as soon as a new message is added it will merrily start deleting messages, so be careful!
