Monthly update post

A short monthly progress report:

• Added the ability to select a folder/project before starting work.

• Added some of the missing mathematical elements.

• Improved the mathematical element selector so that it appears next to the cursor.

• Added Ctrl+Z/Y support.

• Added a command system for quick input.

• Added a window that displays the project structure.

• Added a scroll bar.

• Made various minor UI improvements.

I’m currently working on the formula system. The main components are already in place. The next step is to implement the project compiler, which will collect formulas, algebraic rules, and parsing rules and link them together.
