Hi Manek,
Sorry about the very slow reply – we do almost all support by email (I can see that you’ve been in touch that way now) and although we check in here regularly your question was missed somehow.
To answer the question: There’s no way to completely hide the mini calendar if it’s empty at the moment. It’s an interesting idea though – we’ll give it some thought.
Please follow up with Tockify Support by email if this is still something you’re interested in.
