There are two changes in this pull request. _First_: Add a Repository field so it became better to group in airtable (image attached). _Second_: Add -watched and -watch-since flags. The watched flag will get issues from repositories you are watching and watch-since defines a period for starting getting the issues but if not defined will get every issue (I set the value to 2008-01-01T00:00:00Z). Why did I add this? I watch a few repositories with the intention to contribute in the future, so I wanted a way to keep track of the issues and be able to use the airtable magic to group, filter, and order everything. !airtable-with-repository ps: awesome project 🥇
