Feature request from amenk, posted on GitHub Sep 29, 2015
When installing a new theme, I would add it to
dev/tools/grunt/configs/themes.js
(according to http://devdocs.magento.com/guides/v2.0/frontend-dev-guide/css-topics/css_debug.html#grunt_prereq)
But this file is in the standard git ignore and would be overwritten when doing a composer update (if Magento is installed via composer)
How can we fix this?
Maybe an additional file custom_themes.js which is included if it exists?
