I’ve been trying to add admin panel for this plugin. It, so far, adds up to so many lines of code. But once the feature is available, there’s no more need to edit the conf.ini via FTP. This admin panel will allow the creation of a new GUI and deletion of currently available GUIs.

Custom Field GUI ver. 1.1 has been released to support form element of textarea. The number of colums and rows for the textarea are customizable.
