I doubt I'll ever stream or remote my scanners. There are plenty of online scanners in my home area (some duplicating each other, in fact), and at the end of the day there are maybe 20 frequencies/TGs that I'm interested in on a primary basis, and maybe that many again when I move around in my daily travels.
I see your point about defining beginner/expert modes and I guess it would be arbitrary, but I still think some hierarchy of feature-availability might be helpful for those still on the learning curve.
Re the profile editor, that's unfortunate. I was hoping to be able to completely abandon Sentinel and stay 100% on Proscan for everything. When I connect a scanner to software, it's either to modify the frequency/TGID organization or change some overall operating parameter of the radio. Once the radio is setup as I like, I usually leave the codeplug alone for months at a time, the only reason to reconnect is when a local agency switches to the statewide Phase-II system, TGs re-organize, or similar reasons. But setting up a new radio with a new memory configuration that's as radically different as the x36 or SDS series requires a more robust solution. Sentinel is hot garbage for scan list manipulation, especially when you have to have several copies of the system in multiple FLs, copying sites and agencies en masse, etc. Proscan is the only other piece of software that I found which handles that task with ease.
