As for Filtr pricing, it seems the consensus is that a subscription is good as long as there’s a one-time purchase alternative, so I think I’ll go for that!
@mipstian I’d happily pay $9.99 - that’s my current pain point for value before I start cobbling together some wild custom solution to the problem I’m trying to solve. ;) A sub is very reasonable for a service that requires a backend and continual admin.
