Hi, first of all, great app - been using it for a month now and it's been a very solid experience so far

Would it be possible to add an option for each feed to do the following:

1. Toggle mark as read on scroll on/off
2. Limit (or not limit) the amount of unread articles being kept

A use case that I can think of for this would be for feeds that provide periodic content within the day (i.e. news sites, YouTube feeds that upload multiple times a day). Allowing the user to set a hard limit would be beneficial for tailoring fetched content for specific feeds.

Thank you!
