I find it fascinating how some scientists seem so sure about how things are 'supposed to be'. The Earth's climate has never been static. Almost everything present today (temperature, pressure, percentage of each gas in air, etc.) has been higher and lower (sometimes by a lot) in the past.
What makes anyone think that they know the ideal amount of anything? Higher temperatures will certainly cause change, but why does every prediction paint a 'worst case scenario'?
I have to agree with this, System Settings seems very inconsistent (design) and has terrible information architecture / organization.
I entirely forgot it existed! They still sell that?
Also the features page is garbage. Wall of text with fairly generic stuff while it's still unclear: Can it run Windows? Can it run Linux? Arm64, x64 or both? MacOS?
Your main competition is VMWare Fusion and Parallels. See what features they advertise, make sure you are better and cheaper. Currently it looks like a university project rather than a real product.
There is no dark pattern, it is actually a problem with the way Apple allows developers to sell software on the Mac App Store. We don't have proper control over the process and thus end up with this convoluted purchasing system that is more geared towards subscriptions - which are the real dark pattern nowadays. We sell without any subscriptions - at a very fair price that is extremely competitive with other products. The old upgrade pricing model was a lot more fair to both developers and users and we are sticking to it. This is the only way to offer a free trial on the App Store without requiring a separate installation, which would be inconvenient for everyone.
Far from a university project - but your opinion is yours to keep. It is a shame you are so negative, as it really is a labour of love and a quality Mac app. In fact we have a lot of firsts here, no one has really done a lot of these things (snapshots, suspend & resume, proper dynamic resolution with retina support) with the new Apple framework yet.
