Would be great for long monitoring. To inspect the results the output is terrible, as you can not select and copy easily. More over I am worried about buffer that will get depleted when loggings many messages in 3h window.

Please make a way to store serial monitor into file. It does not need to be perfect. One write to file each 5 min is enough or write when we press the button.

Could be useful as MVP to make serial monitor in CLI version. Therefore user can control what to do with messages.

I Also would love to have this feature, I would use it daily with IDE V:2.03

This seems like pretty basic functionality for troubleshooting. I'm still pretty new to arduino: I'm currently working on my third arduino-based project. The lack of any way reasonable way to save more than about a page of serial monitor output (since #1081 has not been fixed) has caused me problems on two of those three projects.

Is there any timeframe for when this will get implemented or #1081 will get fixed?

Thanks for your work on this project.
