Why don't you add "Scroll is Pan" as in Opera 12 ?
One big default of Windows is obviously the face that its impossible to scroll using a "hand" as in Adobe Reader or in Opera 12 with the option "Scroll is Pan".
One thing I use in Chrome as an extension, which is buggy, is the Extension Touch Scroll so I can use the mouse to scroll the page in holding the click.
What I use to do in Opera 12 and now in Chrome is to add a button or an easy to access parameter like in Adobe Reader to easily switch between the Touch Scroll and the standard text selection mode.
What do you think ?
Thank you for reading and when you add this feature.
