@Seth

Thank you for the detailed feedback. I will make the suggested improvements and upload a new patch.

>> Why is temperature rise an input parameter?
This calculator [1], which is mentioned in the bug description, uses temperature rise as an input parameter.
Moreover, temperature rise is also an input parameter in the Track Width tab of PCB Calculator. The formula used for calculations in this tab is the same formula used for calculating the estimated ampacity of the via in the new tab.
