We used to be able to bring up the import dialog (or open, or save as too) and then drag and drop a file or folder from the Finder to be able to either go to that folder or import that file. Since upgrading to Mojave and InDesign 14.0.1 that functionality no longer works. Sometimes it does but mostly it doesn't.. It now copies whatever you've dragged into the currently open folder in InDesign. This was a real time saver before and is now a pain. It may be an Apple thing but I thought I'd post it here to see if anyone else is having the same problem.
