UI that scales with window size

I'm not a developer so I have no idea how easily feasible this is.

It would be great if I was able to see the entire Periodic table when the window isn't maximized. For example, if I'm working on a chemistry problem in one window that's snapped to the right, it would be great if I can snap the Periodic Table to the left, have both windows be side by side, with the entire periodic table displayed (smaller, obviously).

Attached is a screenshot of the current, undesired behavior.

The current scroll bar solution is a little clunky for me but may be the desired option for some. Maybe a setting option that allows both options possible?

Thank you, otherwise, this is a fantastic Periodic Table app!
