Indeed, I selected the wrong reply command...
Yes, please remove it. IMHO, it doesn't make sense to have this
feature in waterfall mode.
Two ideas:
* What about showing the pixel (or point) size at the beginning of the
waterfall? Ideally, the font itself should be used for displaying
this, however, chances are very high that the font in question
doesn't contain proper glyphs for it, or that the font is cheating
(this can happen for very old fonts), displaying completely
different glyphs for the given character codes. So you should use a
font that actually has the necessary glyphs :-)
My idea is to use Qt's text drawing functionalities for this, because I
don't want to add more complexity to the `StringRenderer` class.
* What about providing control for the waterfall's start, stop, and
increment values? For the default values, I think it doesn't make
sense to have lines for px < 4 or 5...
Well... `ftstring` has those value calculated programatically, and I
directly copy-pasted that part. Indeed, we need to increase the initial
value a bit. If those control options are needed, we may need to find a
place to hold those options in the GUI (maybe better a separate dialog).
* Assuming that you don't intend to implement a waterfall in vertical
mode, the 'Vertical' checkbox should be greyed out if the
'Waterfall' checkbox is set.
Indeed.
