The title of the application is not editable in SlideME. The label name is extracted from the Android Manifest of each application. If you wish to change the name, edit the Android Manifest and re-upload the application. Do not create a new node, update the existing one by replacing the old apk.
For applications that have additional language locales, you have the option to add 'Translations' based on the supported languages your application has been compiled with. From this option you are able to add foreign text to your title of your application in addition to the short and long description fields. Your application can appear in users native language with this "Local Apps" feature from SlideME.
