A quick suggestion: - For the plots, would it be possible to have custom lines by entering different values for the parameters? For example, in my plot, I have a linear fitted line: y = a + b*x. It would be nice if I could enter 0.5 instead of "b" and compare the difference. - Even better, would it also be possible to have multiple fitted (or not) lines & curves in plots? I think upto 4 would be ideal but even 2 would be neat. Cheers Talha PS: Of course, it is always quick to suggest a new feature as opposed to actually implementing it but I think this might be a nice improvement. -- "Remember not only to say the right thing in the right place, but far more difficult still, to leave unsaid the wrong thing at the tempting moment." - Benjamin Franklin (1706-1790) --
