Okay, many topics here. Just to touch on some of your remarks, without hijacking the thread completely. 
I name flows in a certain way so that I have a group of them together, with sequential numbering (it looks like you have a similar system as well). That way I always know which flow comes after the other.
(1-1, 1-2, 1-3 and so on; where all flows starting from 1-2 have WHEN This Flow is started, that is triggered by the preceding flows (1-1), and so on. If this makes sense. :D)
This brings me to:
It looks like to me that the Flow Checker doesn’t show flows with This Flow is started (i.e. 1-2, 1-3…) if they are being called from some other flows, which they usually are in my flows. (I checked this now, just to be sure, and I don’t know if this is a bug or by design, given that it says UNUSED FLOWS OR FLOWS WITH A THIS FLOW HAS STARTED’ TRIGGER in the app. I have many flows that do start with This Flow…, but are not on the list. And, no they are not filtered shrug)
Example:
No Sunset to warm flow in the list, because it gets triggered from another flow.
But yeah, for me, this is a way to go. I used to have many push notifications on my previous Homey, and on this one I am kind of building the architecture first, and then I’ll see what needs (deserves) to get pushed 
What we need is Athom to put the possibility to track “interconnected” flows, and variables, the same way that they’ve started with devices and their respective flows here:
But, maybe now you see why I kind of need to start using the HOOP
Ps. Yeah, I’ve seen that you are a HOOP evangelist in the threads and scince I cannot code js, I have potential of become one, as well.
