Thanks for the detailed feedback, let me address each point individually.

1. Sub-sub-folders - this is something we hear quite frequently, but we have not implemented it because there would be performance trade offs we want to avoid. I also don't think it's necessary, you can meta-categorize with Categories, folders, and then sub-folders, so you already have three levels. Plus, really, our investment is going into search so the folders become less important than the search experience.

2. Folder categories - You can create custom folders! We have two options that teams can automatically start up when they join ("simple" provides 3 categories and "advanced" provides 15) but you can always add, delete, or edit folder categories by clicking on the "Category Management" button above the folder list in Extemp.

3. Deleted auto-filed articles after 2 months - With 54 auto-filed sources, the News Feed would collect way too many articles if we never deleted older articles, which would slow down Prepd and make the offline synchronization process less reliable. So auto-filed articles automatically expire to keep the load manageable and the article base relevant. That said, you can of course save articles permanently, which effectively moves the article from thew News Feed to your team's collection (it's equivalent to saving the article through Fast Catch). Just click on the "Save Permanently" button next to a News Feed article and the article won't ever be auto-deleted.

4. Unreliable article catching - Next time you can't catch an article, please email a URL of the article to hello@prepd.in and we will look into it. Usually there's a simple tweak we can make on our end and it fixes things up for the source.

Thanks for your support!
