the latest version 0.7.0052 has Drag+Alt = Copy. You need to press Alt after you start dragging though, as pressing Alt before a drag results in a Window Selection override.
I think there are issues with the 64bit builds. I don't know what the issue is exactly and don't have a 64-bit machine here to test. It's something I've postponed to my yearly Seattle trip in November. I hope to get Grasshopper running on Rhino5 64-bit and Rhino for Mac then.
just checked! 0.7.0052 works fine under 5.0WIPx64bit - thank you
the only suggestion to switch clone from Alt to Shift so more comfortable to drag while key is already pressed - how do you think?
Nah, Rhino uses the Alt key and I want to keep the same behaviour. Shift is already used to grow selection sets and move objects orthogonally (just like in Rhino).
agree...
and if you don't mind here is one more interface suggestion - if drag link from node to empty space on workspace - 'double click' dropdown menu appear and when node chosen and created it automaticly connected to node you drag link from. i hope im most of cases grasshopper will detect which input of new node will link go
