Feature-value next to voltage sources

[gosh-darn]

I think it's super useful to have the value of a source available at a glance. The current source has it when connected to a circuit. The value of resistors, inductors and capacitors are also visible next to the element. So perhaps it would make sense to do this for voltage sources as well?

It could look something like this:

This was done with text elements which are both annoying to add manually and also do not update whenever the value of the source is changed.
