I am a newbie and impressed by the functionality of this component builder. I have the following idea.
I want to create a component were users can add titles and descriptions for an object. I has to be a multi-language component and i don't want to have these titles and descriptions in ini-files.
Joomla 1.7 has already multi-language functionality. When you look in the joomla tables there are fields created in the content and menu tables. The fieldname is language, type varchar(7). In these fields the language tag is added, for example en-GB or * for all languages.
I would be very nice that there is a Data Type for the Language field that contains the functionality to store the language tag and that will show in forms all the available languages as a combo box that are installed as content in the Joomla installation.
I hope that this is a something for the the to-do list.
