Crowd/personal Funding a Dev to Massively expand Notification options

A Former User

Following on from my prior post I have a query - I understand a little of how open source works - features get developed according to resources, priorities etc etc.

This feature is something I'm really feeling like I'm missing. As such I wondered if I were to crowd source/fund myself a developers time to do this what exactly would the requirements be on pfSenses side?

Would it hypothetically be a package feature or something added to the OS itself?

Depending on the above answer, what languages would be required of a developer to accomplish something that would be acceptable to pfSense for inclusion?

Would appreciate any thoughts or feedback as I'm pretty much clueless on coding!

Thanks in advance
