Hi,
Thanks for the feedback.
Don’t take this the wrong way but I’ll start with an analogy. Imagine you know how to ride a bicycle and you come across a car. You get in it push a whole lot of buttons, turn things, pulled some levers, bought a spoiler and after an hour, you can’t understand why you haven’t won a race, let along start the car.
The two issues here is that you are unfamiliar with Flowx and you want everything to just work for you straight away. So in the first hour, you are jumping all over the place: graphs, edit data, graph ranges, editors, settings, add graphs, noaa website, pro version - you did nearly everything except “Help” 
So I have to ask - did you read the help? in particular Graphs.
Please, instead of rushing, take your time and enjoy Flowx. There is a lot to take in and you won’t learn it in an hour.
I would agree that Flowx has a learning curve. This is because it’s very different to your typical weather app. So it may be confusing but this is because you are unfamiliar. It’s definitely not a mess.
When you get into a car for the first time, it’s confusing, but it’s not a mess. Over time, you will learn and become familiar.
And this is why we have written a pretty comprehensive Help section.
Sure we could ease the new user into the app and I’ve tried to add a tutorial when you first open the app but it just didn’t work. Different people start using the app for many different reason and a tutorial might ease one type of user into Flowx but will completely miss the mark for another user.
If you use Flowx for a week or two - you don’t need to do complex things - you will find the “mess” has some logic. Most users like this logic.
Please take your time and enjoy the app. Don’t try and rush it. You’ll be learning new things in a week or two.
Regarding, “Edit Widget”, please read the help, especially the “Edit Widget” section in Help > Widgets page.
Regarding the gray hump, read Graphs help page - it’s pretty much in the first line.
If I haven’t made my point, please read the help - it’s nearly all there.
Cheers, Duane.
