Prodigy appears to render whitespace many times wider than other characters. This obviously makes sense if whitespace is a delimiter as it makes it easier for annotators to select entities. It does the exact opposite when whitespace is either one of many different delimiters or not a delimiter (i.e. often occurs in an entity). For example, the text below including "VAV T91 looks odd because of the stretching - it makes no sense in this context to treat whitespace any differently to [.-_]. Is there a setting that disables this?
In this case I've generated my own tokens (includes tokens that are whitespace), and set ws: "false" for all tokens.
