Google Classroom Tweaks

Google Clasroom Tweaks currently provides several key capabilities (which - IMHO - are missing in Google's current product offering):

On the Google Classroom tab:

(with all of the columns for your assigments, tests, quizzes, etc., etc.)

1. you can filter the columns to show just those that match a particular text string - e.g., you can show just your tests. You can also exclude columns (e.g., hide all columns that do not contain the text `bonus`, etc.)

The filter supports `or` capabilities (e.g., enter `test|quiz` to match both tests and quizzes) and it also allows regular expressions (e.g., enter `out of (1)?4` to match columns that are marked out of 4 or 14... cool, eh?)

2. with the click of a button, you can highlight entries that have been resubmitted, are missing, have not been marked, have been marked but not returned, etc., etc.
