If you're used to work with more than one stylesheet per website you'll find it kind of limiting that you can only edit the default stylsheet frontend.css in the backend of phpwcms.
This litte hack gives you the ability to edit all available stylsheets resisting in the folder phpwcms/phpwcms_template/inc_css (same place where you'll find frontend.css.
Have a look at the screenshot to see what it will look like
Updated this mod an added an URL parameter, so the edited stylesheet is displayed again after saving/page reload and not the default stylesheet as in V0.1 of this hack
hiho, i included the CSSEdit mod v0.2 but it always overwrites my frontend.css with the changed data and not the stylesheet i selected in the checkbox. :-(
