You don't have to waste your days pining for the software characteristics of the Galaxy Note 10 simply because instead you purchased a Galaxy S10. Samsung has begun rolling out an update that provides the S10 series with some of the characteristics of Note 10.
This involves, most especially, important camera functions. Now you can use Super Steady to record comparatively jitter-free footage, turn on Live Focus while capturing videos, and invoke the front-facing camera's Night mode. You're likely not going to be so loudly clamoring for AR Doodle, but if you want to write in 3D, it's there.
If you are searching for tighter integration between your S10 and your laptop, it is also the update you need. It adds DeX for PC assistance to take your Mac or Windows system with a windowed portable interface, and Windows Link offers a fast track to connect your phone to (you assumed) Windows.
When you can imagine these characteristics on your mobile, there is no concrete timetable, but SamMobile knows that it is now accessible for Exynos-based S10 systems in Germany and Switzerland at least.
It might be a while before your North American device based in Snapdragon is upgraded. Nevertheless, this should help you feel much better if you have wanted parity of software since Note 10 arrived.
