Adam,
Thank you for your response. As per your suggestions:
1. I was able to modify the shortcuts following your method.
2. I was able to bind hiding the scroll bars to a shortcut but only
after changing the way horizontal scrolling is handled in the code.
3. It is allegedly possible to implement the so-called 'kinetic
scrolling' in Qt5 using the QScroller class but I'm new to Qt so.. :)
4. I was able to fashion a preliminary version of this by rewriting the
'convertToGrayscale' function; it is reasonably performant but I'm not
quite satisfied with the way it handles color/shade gradients (I'm using
a threshold) as well as the way it follows/interacts with antialiasing
(for text on gray (as opposed to white) backgrounds).
I'll update you when I have a better handle on #4.
Best regards,
Oli
