Hi,
First, you can now scroll the mouse wheel over the vertical scrollbar to jump whole pages instead of small steps. Over the page it continues to behave as normal, unless you hold Shift, which will also make it navigate full pages.
This works really great, thanks!
Secondly, I also added a scrollbar "page mode", which can be enabled in dillorc with scrollbar_page_mode=YES, which causes clicking with the left button *anywhere* on the vertical scrollbar (including the thumb) to scroll one page down. With the right button, one up. Holding Shift can also enable temporarily this mode (or disable it).
Another good feature, very useful if using a laptop or mouse without a proper scrollwheel.
I also added an option to place the vertical scrollbar on the left, which I'm finding more convenient as it is usually closer to the text.
Nice, this will probably become my default setting now. Thanks for this awesome patch! -Alex
