Hi,

Are there a size limit for the debug buffer (amount of messages displayed in the debug)?

If there is can it be adjusted?

Thank you

Do you mean the amount of characters displayed in a message or the number of msgs in the scroll before they roll off the log?

For the length of the msg there is a setting in settings.js  
I don’t think there is an option for the number of msgs in the debug sidebar, but each debug node has the option to send the msgs to the console log.

There is a fixed buffer of msgs and they roll off the end and all debuts in all tabs share that buffer.

This might be something to suggest as a new feature.
