As development on Arctic seems to have halted, Blorp seems like a promising alternative for its Piefed support, but could use additional quality of life features. Among the most important of these from Arctic is additional granularity in post filtering, ensuring that posts one doesn't want to see can be excluded without impacting the visibility of other posts.
Beyond just filtering keywords, options to apply distinct keyword filtering for post titles, content, URL, OP username, and community name would allow users to preemptively exclude content they aren't interested in. Furthermore, via regex expressions, terms can be combined to increase efficiency and maximize the scope of the filters.
Here's an example of how Arctic handles it, with several of my own regex filters.
My idea was to publish the spec so others could implement it. I have a group chat with the other app devs. I can collaborate with them.
But the main difference is frontend vs backend filtering. There are advantages and disadvantages to both.
Makes sense, it's great if you all discuss about this together
