The idea here is to create a simple, but extensible calculator app. The base app is made for simple pure calculations but also with a history feature so that you can go back to past calculations as they are all saved in a graphically comprehensible mode.

The app is designed to be extensible so that a more complex or scientific addon can be had which will then be able to be selected from the global drawer and showed as its own column/drawer (which is still discussed) to create a rudenementary scientific calculator for desktop and phone
