Start supports drag'n'drop in different places. The most common ways are shown below:
The application is started and the file or directory is passed to the application.
The Finder-Objekt will be added to this Tag.
The URL will be added to this Tag.
The Entry will be added to this Tag.
The main window of Start is displayed and the dropped files and/or directories are passed to the application launched next.
Start also supports the so-called "Spring-Loading". For example, if you drag a file from Finder to a tag and wait here briefly (without releasing the mouse button), Start switches to this tag and displays the contents. You can then perform the drop on an application of this tag.
