Wouldn't killing the app accomplish the reloading?
I renamed the package and changed all the internal imports to html3text, and have a working script now.
It's Pythonista 2. I bought 3 but haven't gotten around to switching.
The problem is that the built-in html2text can't deal with missing CSS definitions, which affects pretty much every page on the web, unless you implement your own handling of <link rel="stylesheet">.
