I would like to see LogCat run the other way, printing the most recent output at the top. Is this possible? So far I have not been able to reverse the output.
If you want to understand the ADB protocol - https://github.com/cstyan/adbDocumentation this is a great reference
Try mucking around the source code? I'm sure with a couple of tweaks you can get this to work. (Update: the link is dead - it was a link to logpanel which a developer sees)
Instead if your familiar with Python - you can write a script - based on this https://chromium.googlesource.com/chromium/src/+/master/build/android/adb_logcat_monitor.py
I agree, it is a nice feature that should be activated when "Time" is clicked. You can put up a feature request on b.android.com
