I find Xcode tabs to be very cumbersome. I use Cmd+Shift+O to open files into a tab. Is there any way to get Xcode to not overwrite the current tab? Instead I'd like Cmd+Shift+O to open the file into another tab and if the file is already open in another tab, simply switch to that tab?

Has anyone had issues with installing and running a watch app using the latest beta software?Xcode 10 beta 6iOS 12 beta 8watchOS 5 beta 7I get the following error alert when I try to run/debug my watch app on a read device.Unable to install "MyWatchApp"The certificate used to sign "MyWatchApp" has either expired or has been revoked. An updated certificate is required to sign and install the application.If I switch to latest released software, everything works fine.Xcode 9.4.1iOS 11.4.1watchOS 4.3.2Every target in my project is set to "Automatically manage signing". I've removed all the provisioning profiles and let Xcode re-download them.Nothing seems to work to allow me to install my watch app on the latest beta software.

How can I split the editor horizontally and have the same file in both the top and the bottom?
