Right now exporting assets or artboards re-creates the file structure as defined in the layer name. For example “Components/Map/Pin” will export the Pin asset in a Map folder, inside a Components folder.
This is annoying when all you want is quickly share the Pin asset with someone. I wish there was a “Flat” export option (next to the prefix/suffix options) that just saved the file without any folder structure.
This is a really nice suggestion, and I can already tell you we’ve started to discuss it internally.
As a workaround, you can Copy (⌘C) and Paste (⌘V) an Artboard/Element and paste it wherever you like and Sketch will copy (and paste) a PNG of the selected element.
