Core

• It is very hard to style it, because of strange constructs everywhere
• The output cannot be validated
• For the new upcoming Introduction Package we need hooks for the 1-2-3 installer which makes it possible to overwrite and add steps

• Make parts of the install tool templateable
• HTML which stays in the code, must be simple, like text within plain paragraph tags
• Take care of clean HTML which can be validated
• Add hooks to class.tx_install.php
• Start implementing new ExtBase like directory structure, right now only for Resources.

More information:
This project was started at the T3UXW09 and has it's own project page on Forge: http://forge.typo3.org/projects/show/typo3v4-installrefactoring
It has not been finished yet. In the second phase we will try to split up the huge class.tx_install.php file into smaller chunks, so it is better readable and maintainable.

The contents of the zip contains the images and should be unzipped in the folder /Resources/Public/Images/ of the extension in typo3/sysext/install/
