SnapLogic’s Copy/Paste feature is amazing and I use it a lot. It would be really amazing, if there were a way of copying/pasting multiple selected snaps at once.
@omair, this feature does already exist. Using Windows, you can hold the ctrl key and click to select multiple snaps. Then right-click one of the selected to copy/paste the selected snaps. You can also shift-click-drag a selection box around multiple snaps. I presume a Mac provides similar capability.
It is similar on the Mac; just use the Command key instead of Ctrl as the modifier.
See the Keyboard Commands page in the documentation.
