I would like to see a way to filter out certain apps as well.
I think that Zappl post should remain in the zappl realm. The shorter post have a place in the STEEM blockchain but I think that steemit should offer a filter where you can disable certain categories frombeing a part of the main feed. I do use zappl about 2 times a week but find the brevity of the post unbecoming of a steemit blog post for the most part. Filters would make this 100% appealing. We have NSFW filter so we know it can be done. Perhaps this may something we find in Hardfork 20.
