Hello,
I've just added something into 2.1.1 which I'd like comments on. In a
spectrum window (with focus) if you type "d" then it draws a
(quasi-permanent) crosshair at that location, and then instead of the x, y
position being reported at the top (in the button to the right of the
Strips button) you get the difference to that crosshair. If you press "d"
a second time it moves the crosshair. If you want to get rid of this and
go back to the normal situation then you type "D".
A couple of comments.
In theory we could give both the actual and the diff values, but that
would take more real estate, so the current situation is a compromise.
And currently it just does ppm. So the question on that front is do we
need the ability to display Hz even if the window shows ppm. (Of course
the windows don't have the ability yet to be drawn in Hz, but that's TBD.)
And if so, what sf should we use to do the conversion? (We could add a
way of specifying that somehow, the only question is where.)
And because of the way it works, it does not do z. I guess on that front
if you clicked on a peak and then a second peak we could show deltas
somehow, but I can't think of a good way to make that not clunky to use.
(If computers were a bit faster or the code a bit cleverer then I guess we
could try and figure out what peaks were under the cursor as it moved.)
