Calendar navigation

I frequently go back and forth between months and have to scroll back to the top of the page to go to the next month. I understand the navigation buttons (including what month you're on) at the bottom of the page has already been suggested.

Also, whenever there is a submission, it would be nice to stay on the month you've made the submission for (i.e. I have been working in May 2023 and each time I make a save, it goes back to September and I have to go back to May to make any necessary changes).
