Hi Brandon,
The idea with the update is to make it easier to work with a variety of formats. So rather than pasting into a grid, you paste into that window then Skyline presents your values in a grid where you can readily define your column types.
But if I understand you correctly, you are missing the ability to perform edits in the grid once you have pasted your transition list into Skyline - is that correct?
Thanks for using the Skyline support board,
Brian Pratt
