Forked from https://github.com/jreinke/magento-admin-theme and update for private framework.
Switch theme from in the footer.
You can also add a custom theme from Magento 1.9.x using theme.xml and a parent declaration. This has been added to the Flat Gray theme. When you create your own theme make sure to define a parent and define the new theme in a module configuration file as following:
<config>
<adminhtml>
<themes>
<nashpharma module="bubble_admintheme">
<label>NashPharma</label>
</nashpharma>
</themes>
</adminhtml>
</config>
Less files are also added to be used with our private framework. Make sure your Less compiler picks up the files if you want to use them.
