Even if the Plain Text input is chosen it allows for pasting of HTML but it is invisible. https://kb.blackbaud.com/knowledgebase/articles/Article/191174 This makes no sense.

Could we also get this to filter out tabs and other special characters please? Copying from Google Docs has inserted these this year and required manual cleanup.

Preach!!! I have comments that look correct in the old report card builder but now are missing spacing in the new one, no matter how many times we said copy plain text or don't copy from Google. And they used to recommend word instead but that's not an option anymore since most don't have it.

This has become a large burden for our small number of grading managers, as most teachers use Google Docs to write and save their grading comments before pasting them into our BB LMS. This became a common practice because it is easier to collaborate with reviewers in Google Docs than it is in the BB LMS, which has restrictive writer/reviewer back and forth editing capabilities. Having to go through hundreds of teacher comments to clean up every instance of this pasting hiccup is a problem. 

Yes please!
