You should play with the FontForge pen tool in a quadratic layer. It behaves roughly as @davelab6 requests in https://github.com/fontforge/fontforge/issues/3803 . (You may have to drag at first to get...

My only strong opinion is that if you're going in the console direction for a design tool you should keep the console stuff "one-handed" (as it were). And given that...

For truly general text arguments like point names you'd presumably just switch to typing. But in this domain those are fairly modest and rarely-used: filenames, font names, point names. Glyph...
