At present in order to add files or folders to be searched, one has to use the in-program file browser tree view. While this is a good implementation of the tree, there are better and easier ways to access the necessary files, especially if they are nested deeply in the file system as is the case on many systems.
I propose that several new modes be added to the application to select the files to examine.
1.) a "Browse" button should be added to the "Select Files" tab which will bring up a standard "Open File..." dialog which will allow either files or folders to be selected. alternatively, a different button for each "Add Folder" and "Add File"
2.) a Text Area where a user may input directly the path to the file or folder they want to add.
3.) enable drag and drop so that a user may click and drag their file or folder onto the window to add it to the list of files/folders to be examined.
