0.1.7-holding session graph!

In this update, I'm introducing a graph that allows you to see all the holding sessions you did during this year!

To see it, click on the "history" button of the main panel:

This will allow you to keep a record of your holding sessions and also share them with others. What do you think? I can't wait to see your screenshots!

As always, all feedback is welcome! This is a tool for all of you, so please let me know what you would like to have next!
