I think it would be great to have a via calculator as a new tab near the trace width calculator. This is especially important for high-current and high-power applications. Just like we need to know what trace width to use to carry different currents, we need to know what via diameter and/or how many vias we need to use. Here are some sample calculators:

Update: this tool has a ton of features worth duplicating as well. Please take a look at what it offers, and let's get all of the most useful features it offers into the KiCad calculator as well. I don't want to have to turn to other tools, I want KiCad to be so complete it's all I need. Thanks.

The patch is based on this online calculator [1]. The only difference in functionality is that the temperature rise parameter has been made variable.
