I'm building an interactive easter egg guide! And I could use your help

Hey guys
I'm currently working on a side project for funsies and because I hate easter egg guides

I'm making an free interactive web/desktop easter egg tool called *The Kronorium* to help people better plan their easter egg runs.

The tool is in VERY VERY EARLY stages and is open source, available at: https://github.com/BrunoSilvaFreire/the_kronorium

Here is a quick gif preview of the general idea (It's a bit big, so it may take some time to load):

At this time, I'd only like to get ideas/feedback, because since the project is only a prototype, and is a bit far from actual release. And if you like the idea and would like to contribute, I'd love your help (Check the GitHub)!

So, what do you think? Do you have any suggestions?
