Saving a file should not highlight the extension
When saving (copy, exporting, etc), the save box highlights the extension. This should not happen. Soon as you choose a different format, the extension is no longer highlighted (which is good and how it should be). The extension should not be highlighted. This Illustrator bug happened after the Mac Catalina update.
This is SO messing up my workflow. 20+ years of using Adobe apps on a Mac, and now this change? What the heck, Adobe?!??
