As for remote control via smartphone, a simple way to do it would be to
leave the USART2 pins available for external serial connection (that is PA2
and PA3), from there, an external additional bluetooth serial adapter
(HC-06 for instance) would make the commands available to a smartphone.
Currently PA2 and PA3 and used for the switches, but I can see that other
I/O pins are available.

I would like to have the option of controlling my VNA via a smartphone or

I believe this is the way the industry is going for portable
instrumentation.
I saw two examples this summer.
The Army Corps of Engineers is surveying the beaches here in New Jersey
for coastal erosion. The GPS receiver is mounted on a pole with the antenna
on top and the data was collected on a tablet. This remote interface was
handy because the receiver mounted on the pole had to be placed in the surf.
I had a service call with Comcast to replace a faulty cable box. The tech
used a test set which was controlled and monitored with his smartphone. He
used it to check signal levels at various points, some with were tight and
he could analyze in a comfortable position instead of crouching down.
The MetroVNA and Sark VNA have bluetooth, it shoulc be included in the
next version of nanaVNA.
