Spelling aid idea: automatically expand "it's" to "it is" so that you can immediately see where you should have written "its" instead.
@edavies That gets tricky. Maybe you could just fix that manually then.
@deshipu Yes. At first I thought some simple pattern matching would get it mostly right but on reflection I'm not so sure.
“Why's the train not there?”
“It's left.” (has)
“It's broken.” (is)
“It's broken down.” (has)
“It's derailed.” (either)
@edavies Yeah, you would need to find the verb and then guess the tense. Gets even more fun when you consider irregular verbs...
@deshipu Except when it should be expanded to “it has” of course.
