Drag and Drop feature for attachments
Create an area on the "Transaction Attachments" window that would allow you to drag a file from file explorer or other programs that show the contents of folders so you don't have to click the add > add file > select the file to upload. Just drop the file in the area (see attachment of mock-up) and it process the same as the add file. Then click done to close the window. This would help for those of us that scan our receipts to a file first and then enter the transactions in Quicken.
