1. It would be nice to have configuration checkbox in email-ext, to attach zip file with job console logs from failed slaves, like:
failed_console.zip:
slave1_console.txt
slave2_console.txt
slave3_console.txt

Currently, the build.zip from master node is ~useless because all interesting info is at slaves and requires manual work to extract.

2. Also, the build.zip attached in the email-ext contains file named "log", can you change it to log.txt to let "double click" open it in notepad automatically?
