The rather simplistic transformer object has some problems and presents an obstacle for defining and simulating many RF circuits.

Some suggestions:

Transformer symbols should have a small "p" and small "s" to denote primary and secondary.  After several flips it becomes impossible to tell which side is primary and which is secondary.

For RF transformers (toroidal transformers) the turns ratio thing needs to be changed so we enter primary turns and secondary turns as actual turns count.

For RF transformers we need ability to enter core type or permeability factor.

The simplistic "XFMR" designation needs to show more information pertaining to transformer characteristics.

Flipping transformers horizontally or vertically seems to loose track of which side is primary or secondary.

Transformer rotation by 90 degrees should be supported.

The laminated core representation of transformers is not technically correct for RF type toroid-core or air-core transformers.

Still, for the price this is an excellent educational tool, and one that does have great potential as it evolves and grows. If one breaks larger and more complex circuits down into small stages and tests those individually, it can be a great tool for even larger circuit design evaluations.
