A Developers Funding Program is a great idea that could boost development on the Q2A platform, but the slowdown in updates is also a natural part of the project’s lifecycle.
Early on, there was a lot of core work to do, so frequent updates were common. Over time, as the platform matured, fewer major changes were needed. Now, development mostly focuses on smaller improvements and fixes, which tend to be bundled together rather than released individually.
One major improvement I could see at this time, is a redesign on how themes work. They could be more flexible, something like WordPress’s system. However, implementing this would require significant core changes, which might only be possible with dedicated funding with the amount of work that would take. (Plus would be hell for theme developers to update their products xD )
Although a Developers Funding Program has been discussed before, it hasn’t become official yet. But it's nice to see people starting threads, that means there's people who'd be down to help the community grow in a financial way.
I'm not saying one could quit their daily job to become a full-time Q2A developer, but a lot more time and effort would be spent towards it. Maybe even attract new contributors to the project.
