A video tutorial might be a tad of overkill at this stage, and prone to becoming VERY quickly irrelevant any time Gufi or I do work on it. Once it matures, though, it's a fine idea!
Let's add another "please": better automatic colours! This would be easy to fix, I know how it's currently done...

OK, I totally agree. For now, the order of the numbers in the list when you mouse over the graph (I assume that you saw that?) is that in which you added them, NOT that in which they are in the adding view. So, I recommend:
A) change colours first
B) add them sequentially such that you know the order
This is the work around I've been using... but yes, it needs to be much better.
I also suggested having numbers in one side of the other all the time, as well as, or instead of, the mouse over numbers.
BTW, given that you're probably viewing the same numbers all the time, on a real car, unlike me, you might find the "saving colours and ranges" feature useful. That needs some refinement too, like ability to only define the colour, not the range, and have profiles to load, rather than just the same set always load, etc.
X and Y axis ( numbers on the vertical and horizontal axis)
Unless you mean percent, you'd need a set of these per value. I'd like to see min/max displayed all the time, I think the eye can do the rest, more discussion here?
Now you've got me thinking about this, another thing that is missing is marks. IE, in ms logs, if you slam the space bar, you get a reference point in the log file, often indicated by a vertical line. FreeEMS may have a richer set of such marks in the form of error packets that the device sends out. Additionally, it would be great to enter marks INTO the log file from the UI with comments etc to document what you saw "at this point, i floored it, and the wheels broke loose briefly" or whatever, and save it, so when you next open it, months later, you remember what went down.
To that end, import/export functionality so you can suck in a file in X, Y or Z format and pump it out in X, Y or Z format, in any combo. Or perhaps just IN in all directions and out to some internal verbose structured format.
PS, it's great to be discussing this with another user! :-) Hooray for their being two of us! I'll try to make that number much larger soon. Sean uses it too, a little, but rarely posts, even in his own threads.
Keep the feedback and suggestions coming, anything, minor, major, whatever, if it's documented, someone can fix it, if not, it might get forgotten or get left un-noticed.
