A Developers Funding Program is a great idea and would definitely help engage the development of the Q2A platform, but the slowed down development is also a normal organic curve.
Well this is also an organic curve,
In the beginning there was a lot of things that needed to be developed and sanded before the embryo became a fetus, so commits were being pushed often.
As the years go by, this things start to get more and more in shape, until eventually they reach its final form, so less commits are being pushed because the fetus is mostly done formed.
Once the fetus is final formed, the less necessary feature implementations are required, so this becomes the miscellaneous phase. The miscellaneous phase, it's about all the little miscellaneous things that reinforce the product as a whole, this is where the hair, eyebrows and other features happen, right.
As they are little changes, there's no point in pushing them one by one on a product update but it's rather smarter to gather them all into a bulk update.
So all this little things get queued, in case a possible major future update comes in motion.
So this is why I say this is a normal organic curve.
An update I believe would be a game changer, is the way themes are implemented. If the way themes were handled in Q2A had the same concept as WordPress, this would be huge. Themes would become a lot more malleable and extendable. But that would require a MAJOR core transformation. in which maybe it would only be possible if there were a Developers funding program.
A Developers Funding Program has emerged before in previous conversations, but so far hasn't emerged as an official program. But that can't also happen if the developers don't gather around and discuss this possibility, which is good you started this thread to come to attention that there's actually people that'd be down to help the community grow in a financially way.
I'm not saying you could quit your daily job to work solely on Q2A, but a lot more effort and time would be spent towards it. Maybe even new developers would join.
