This is unfortunately a tragedy of the SONAR development process. The ability to remove a chunk of data from a multi-track project and close the gap seamlessly (what other DAW's term ripple editing) is such an essential editing process that the failure to be able to do this as a simple procedure has seriously impacted the utility of the DAW. Prior versions had a delete space that came close, and is now less than fully functional. There are kludges that will allow you to accomplish what you want, and I assume that the programming involved is not trivial, or the problem would never have surfaced. Nevertheless, the priority of fixing this, or more accurately making the original concept work as expected, cannot be underestimated. We all look forward to the success of the Cakewalk team in this effort. In the meantime, we should rejoice that they have let us change the colors of the interface.
