Support drag and dropping files from search
Feature summary
Currently when searching in the activities overview, files results are shown however these items can only be opened with the default application which isn't always desired. It would be useful if we were able to drag the items from this list and drop them on an application window like we can from nautilus. This would be useful for uploading files to the web quickly or opening a file in an IDE amongst other use cases.
How would you like it to work
- Open search and search for a file
- Mouse over the file and hold button 1
- Drag file and shell will show a semi-transparent indicator to show the file has been grabbed
- Shell returns to the window overview layout so you can hover over an application to bring it into focus and drop the file onto it
- Application receives file as if it was dragged from nautilus or the gtk3 file picker.
