Newism releases override.css
Add-on developer Newsim launched override.css a few days ago, allowing you to easily override the default theme in the EE2 control panel.
This isn’t really an add-on or a theme (you just download and copy the css file and images to the default theme directory) but it does nicely tweak the default control panel.
The current design of the default CP isn’t to everyones tastes. Override.css is a stylesheet that takes the default CP theme and adds consistency, improved contrast and greater user experience for content managers and ExpressionEngine implementors.
The override.css download is not free. Newism cites the amount of time required to support and update the css file. It is, however, not expensive at its $AUD 9.95 (about $10.23 US) sale price.
