1. I want to be able to embed this calendar in the sidebar, other free plugins on the market have this feature and I really need it for making websites. These days I don't think many websites purely have a page just for a calendar, for example for a sports club, people need to know the class times so these need to be in the sidebar.
2. calendars need to be AJAX these days in my opinion, reloading the entire page to navigate to the next month is a really poor user experience, especially if it's in the sidebar
These are the reasons I can't use your plugin at this time, but I really like WPMU DEV and if they make these fixes, I will happily use it
