Big fan of ‘smart filters’ / ‘rules’ - I use them all the time in various apps. BUT I sure hope that developers smarten up on how people use this functionality because I have hit limitations in building filters pretty much everywhere. The one exception so far is Readwise, BUT to build a filter there is not simple because you need to know so much about the formats they use. It gets real complicated real quick.

I know they are working on a simpler interface to their rules engine. I hope they don’t fall into the trap of providing a limited set of options to their customers.
