rinaldok, as I answer this please don't read what I'm saying as an excuse. Please see it as a story why we're not where you're wanting
just yet.
The reason notes were separated was because of the lack of space on the logs page. We wanted users to mostly see raw numbers on that page and as many of them as possible, which is limited on a mobile device. This is the same reason we kept notes "hidden" on the first version, simply because of space. That said, I see your point and can even think of numerous other scenarios where user's observations would help further explain why the test results look like they did. That said, let me explain why I'm leaning towards keeping them un-connected as they are. Currently the only way to really see a long term trend using PoolMath is by scrolling the Logs page and forming a picture in your head concerning trends. It's almost impossible to see any long term items that maybe occurring currently as you're always looking at a small part of the picture. This leads its way to graphs as they do a great job clearly showing the user long term trends that are occurring. As is we've setup and tested graphs in Beta but ran into a problem........they looked/acted horrid on a phone. Maybe this is simply me but I had a VERY hard time sorting the data out on my phone as even in landscape it all looked very small. It just wasn't working for me. This lead us to look at larger screened devices as the answer to fix this problem. Tablets or Computers do a GREAT job at showing the big picture when it comes to data. The larger screens really shine verses the smaller screens of your phones. After looking at our options we felt its made since to go ahead and start aggressively working on a Windows 10 version of the App to bring the PoolMath App to your desktop/laptop. Currently we're about 99% of the way complete. In fact there's a live and working version on the Windows App store, but we've got it hidden for now. Jon (the developer) is out of town on business and we don't want to do a public release without him being around to address any issues.........we learned what happens there the first time.

Once this is complete then our attention shifts back to graphs where you can see trends better.
So how does all this address your request?? Our thinking (maybe right, maybe wrong) is once we launch graphs the majority of end users will use graphs more than the Logs pages to see trends. They won't even see the notes that much......but that doesn't mean the notes are pointless. Here notes can help explain why a test result occurred as it did once the answer is known (IE A large drop in FC can be explained by having a large swim party). To help address this we've got an idea but I can't toss it out there just yet as we're unsure how much altering of the code we'll need to do to achieve this.
Cliff notes as I know I went around in circles:
1. Graphs are likely the future
2. Windows 10 version created mostly because we wanted the big screen's to show large amounts of data
3. Our guess is most people will use graphs verses the logs once we launch them
4. We've got an idea to tie your the graphs in with your notes IF we can make it happen technically
