Rune,
I'm still hoping someone can help me understand the new TDR impedance measurement display ( see message /g/nanovna-users/message/6520 ). One other thing in regards to the TDR display which I hope eventually makes your "to do" list is related to the attachment.

The cable assembly in the attachment was made up of a 0.3m length of RG-174, a BNC bullet and a 1m length of RG-223 terminated in a 50 ohm load. The TDR measurement display showed a peak at around 0.3m for the RG-174 cable and then another peak at around 1.3m for the RG-223 cable. Very happy with the numbers, but currently NanoVNA-Saver only displays a marker for the highest peak, which as shown in the attachment, is not always the only peak of interest. It would be great if an additional user selected marker could be enabled to more accurately mark additional peaks.

Best Regards,
