Edge Slide Tool - Upgrade

Hello, I want to discuss this little but very useful tool "Edge Slide". I think it need to be improved.

PROBLEM of current "Edge Slide" tool:

• you can't slide with Duplicate and repeat selected edge/s shape along sliding way (I think it the most lack feature in this tool)
• slide on specific value

SOLUTION a little mock-up

DESCRIPTION of new elements:

• Distance - slide edge/s on specific value from -infinity to 0 on the left side, from 0 to infinity on the right side
• Duplicate - duplicate selected edge/s on factor from -1 to 0 on the left side, from 0 to 1 on the right side or distance (values above).
• when Duplicate checkbox is active, checkboxes Even and Flipped are disabled because we duplicate specific selected edge/s on Factor or Distance and want to repeat current selected edge/s shape (otherwise it's another Loop Cut and Slide)
• if checkbox Clamp is active we can only slide with duplicate on distance to the next loop, as it works now

My current workaround it's a bevel edge loop with specific value, with profile 1 and segments 2, and then delete unwanted loop on the left or right side. It's so long and inconvenient. And if its a manifold loop you cant bevel it this way...

One more mock-up and new feature Slide Proportional.

Original edge: Slide with Factor and Proportional Editing: Slide with Factor, Duplicate and Proportional Editing: Start-point is the Active selected element (in this case active edge at the bottom), End-point is the last point in selected loop. Reverse Falloff - changing falloff direction for some cases if you don't want to click-define new Active selected element.

If closed loop is selected then Start-point is the Active selected element , End-point is the farthest point from Active selected element in selected loop.
