textcat.manual allow user type in

Hello, I'm trying to classify a set of texts. However, their categories are not fixed. Can I add type in feature to one of the choice, like Other (User Type In Category)?

I think text_input might be a solution for this, how can I start this feature in command line? Thanks!

Yes, I think using a custom interface with two blocks makes sense here: one choice block and one text_input block, very similar to the example here: https://prodi.gy/docs/custom-interfaces

You could write your own custom recipe based on textcat.manual and change it to use "view_id": "blocks" and include the "blocks" config setting in the "config" returned by the recipe.
