Add the ability to browse to a new source file rather than entering file path as text
Would make it much easier to use the same layout for multiple files if we could browse to a new source file. The ability to change source by entering the file location is nice but inconvenient if you are pulling files from different directories. (Running on Mac)
FYI I posted this, and found that functionality is already there, just not in the Inspector window. File>Load Source File changes the source file for the current layout. Woo!
