Sell apps within base44

Users should be able to sell apps within the base44 application for others other use and adapt. Perhaps with once off or subscription terms. Especially if a user has built a really good back-end stable app platform that could be adapted easily by other users. This would save an enormous amount of time. Perhaps the platform could use AI to rate apps on how robust they are etc - so that buyers have an idea if they are buying rubbish or something good. Could opt for cash or extra development credits as payment.
