This idea has been developed and deployed to Canvas
Allow the option for a fill-in-the-blank answer to *contain* a specified term/word instead of having to match a word exactly. This would cut down on the instructor having to think of all the possible variations/mis-spellings of a certain term that might occur. Sometimes just setting part of the term for an acceptable answer covers a lot of acceptable submissions.
Additionally, and perhaps a separate issue, it would be nice to be able to set a character limit on what students can type in for their fill in the blank answer (i.e. it would be nice to limit them to writing a word instead, sometimes students are compelled to write sentences).
