New post editor and HTML.

Alright. The new post editor is not good for the HTML of templates and such. Even simple codes like this one:

Code:

[list][*] - [/list]

Look like this after you edit it:

Code:

[list]
[*]-
[list]

[*]

It doesn't look good, so I would like it to change. Also does the new post editor change the HTML, and when you want to edit it, you don't get the right code back. I hate this allot, because it makes my templates look messy after I have edited them or used them again. Can this be changed, please?
