Hi as there already is a similar thread, I'd like to bump it.
After using sublime for a long time I got rid of the scrollbars using overlay_scroll_bars: enabled as I never use them except the horizontal one when lines aren't wrapped. But this is no drawback either. I love to use the mini map and that's all I need most of the time.
I would like to have them hidden completely. No scrollbar, no overlay scrollbar.
Fancy would be having only the horizontal one but only when lines exceed the screen space when hovering over the bottom border. When working on my laptop, shift + touch pad works fine but sometimes the horizontal one would be nice to have.
