Hope the writing’s been good to you.
Just a quick suggestion and I admit it’s a little anal, but still thought it might be a good idea if it’s not too hard to implement. In preferences, I think it would be great to toggle scroll bars on and off while maintaining the ability to scroll pages and windows using our input devices (mouse scroll wheel, two finger track pad scrolling, etc.).
Just a thought. Would be especially useful for me when a project becomes crowded with information - like with index cards, etc. Every pixel counts.
Thanks & all the best for your endeavors!
