Going forward, we will continue to make improvements to the current software. One of the most requested features is improving the forum's usability on mobile devices, and that is already being worked on.
Donate a good amount of money to the SMF team, ask them the improvements you have in mind, ask them to work a dedicated team for our version of SMF. I don't think you will require even a $100k investment.
It's good to know that you finally decided to break the loop.
