Right now if you go to export a layout over an existing file, you encounter a problem. Let's say it's a .png. If you click the yellow folder to find the PNG you're looking for and double click the PNG, it should select and OK the selection. Instead, it ... opens the PNG. You're inside the PNG in the browse box, and it says 'this container is empty.' This runs counter to almost every other application under the sun; PNGs are not conventionally conceived of as a container, especially in the context of exporting. Further, if you click OK at that point, you get an error when you export.
The ask here is to just select and OK when you double click an existing file, as is convention.
