Thanks for the feedback! The underlying component with the Compare Files window has changed. The new component is newer and quite a bit faster than the old one that used to be there. The old one also had no way of providing “merge” capability, which was needed for Team Coding. I tried to pull over all the major options from the older component so it would be a fairly easy transition, but I may have missed a few things. So please feel free to let me know if there’s something you need that’s missing.
You can copy individual lines from the LHS and RHS simply by pressing Ctrl+C. I was trying to add multi-line copy for the left and right-hand sides of the compare window and noticed significant performance and syncing problems between all three editors when that was enabled. Since it was fairly late in the release cycle, I figured it was best to leave that out rather than introduce other problems. As a result, the easiest way to do a full copy from the Compare window is to click the “Enable Merge” button and copy from the Merged Source panel. (I realize as I’m testing this that there’s a bug where the Merged Source isn’t initially populated when doing a basic compare. That will be fixed for the next beta.)
Alternatively, if you're only looking to show the differences, you can click on the Report button. That will show you a report of all the differences between both files:
The hint popup is a bug. That will be fixed as well for the next beta.
The Switch Sides button should be available for both modes (compare vs merge) of this window. It’s located right next to the “Enable Merge” button.
The Merged Source will always initially be based on the code in the left-side of the compare.
Feel free to let me know if you have any questions, or if you see anything else.
