This will not be updated to 4.5, as this is now a built in feature.
This is a simple plugin that alters the amount of text/image shown in quote boxes. The changes are purely visual, no permanent change will be done to the stored post. It is also backward compatible with older posts. And everything will be restored if the plugin is disabled/uninstalled.
If you're having issues, please send me a personal message. Do NOT post it as a review, as I don't monitor those.
