I might as well kick in my 2 cents.
I would love to have a tool to show the code for a single (first) character of selected text (on Status line)
The problem was the display font did not have support for the character (BV or CV)
So what character do I replace or embed a font that supports?
I had to resort to a old DOS Hex file editor to learn the (in this case UTF code)
I would not be unhappy if we could set a preferred Open view.
