Yeah. It would take a lot of time, I’m just thinking of things like TrueSKY, VXGI, AHR, or whatever comes along next. It’s difficult for the average user (or artist without programming knowledge) to integrate multiple plugins themselves without breaking things, and it gets harder to maintain as you start adding more from various sources and branches. Just seems like the logical progression to add when there’s already a marketplace that’s capable of handling all of that.
Of course, I say all from the point of view of someone that wouldn’t know the kind of work that would need to go into that. As useful as it would be, it might not be worth the months of effort that it sounds like it might take.
