This mod operates entirely through console commands:

/CTbind [name] bind the entity under the cursor as a probe (with optional label). cannot be used while a trace is running.

/CTunbind unbind the probe under the cursor. cannot be used while a trace is running.

/CTclear cancel any running trace and unbind all probes

/CTshow mark all bound probes for a short time

/CTstart start a trace

/CTstop stop a trace and write out a .vcd file to script-output

Traced signals will be truncated to the smallest whole hex digit size that can contain their full range, or to a single bit if possible. Multi-bit signals will trace 0 as Z to better highlight pulsed values, and to reflect the no-zeroes nature of circuit wires.
