FEATURE: Scrolling locks when double-tap, or long-press, in empty space in a browser

[ElectricEgghead]

My laptop doesn't have two-finger scrolling. Could you make this extension lock when double-tapped once in the empty space in the browser? Or if I long-press my touchpad (maybe one second) the scrolling will lock? Preferably, the cursor doesn't move with the page, or show, so it emulates two-finger scrolling?

Thanks for this extension. It's helping me navigate a lot easier with this new laptop.

My setup:

• Mouse button used when scrolling: Neither. I double-tap on my touchpad in empty space, then drag my mouse up/down. Left, technically, I guess. Lol.
• Chrome version: Using Torch, 57.0.0.12335
• Operating system: Windows 10, 32-bit

Hi, and thanks for your suggestion. I will consider this, but I don't think you can expect it to be implemented any time soon. I'm maintaining this on my spare time, and I don't have a lot of that nowadays.

If you're able to, you're welcome to try forking and implementing it yourself. I'd be happy to accept a pull request.

This should work all the way back to Chrome 37. It's not pretty and I won't be submitting it for a PR (at least not until the bugs are ironed out), but maybe it'll be useful for ya.

Some bugs I noticed:

• The first movement after the pointer locks (ie. after a double-click), the page is scrolled up by a full page's length plus a little bit. If you happen to be at the very top of a page when you activate it, this still applies. So just.. scroll down a lot, I guess.
• Gliding doesn't work yet.
• There's a way to wiggle the options into a configuration that locks the pointer when you double-click the middle button. This isn't the default, though. I don't think.
• The double-click time limit is a static 500-milliseconds. This isn't really a bug, I just found it funny that Chrome couldn't pull that information from the system. So instead of writing an OS-dependent mess, I planned on putting an option in allowing you tell it how long a double-click should take. I haven't gotten to that yet, though.

Good luck
