Add Duplicate Selection on Drag
There are little things I like from Adobe Illustrator but there is a very handy one that when you don't have it you miss it, I know there are similar options in Inkscape but none of them are as easy, fast and "natural feeling": the ability to duplicate your selection just by ALT + click + drag.
I'm adding the feature the Inkscape way
If enabled,** I suggest to use ALT key modifier** as it is compatible with the other modifiers, because this is how Illustrator works and users switching to Inkscape will feel natural and because there are not many other options left...
In the way I found a bug and fixed it: when moving objects using the SELECT_FORCE_DRAG (or the new SELECT_DUPLICATE feature) and snapping ON, it didn't work. Now it works for both of them
Let me know what do you think
