More joomla Standard

My wish for the Version 3.0 that you use more Standards for example:
1. Editor: Use the Editor which the user has in his profile.
2. Langagefiles: Use the Language-file-folder: /language/en-GB. I wish also that I can
store my translation for example in /language/de-DE because I have no time to look always
through all the vQuiz-folders where the special languagefile which I have to change is.
3. Use for pictures the joomla folder /images or /images/joomlaquiz. For now it is only possible to upload from the harddisk, but I cannot choose from my already uploaded pictures.
This is not userfriendly.
Whold be nice to think about it.
