Vizzy editing with text code

Just an idea to make an option to edit a Vizzy code with a text code, like in usual programming instead of visual click-and-drag blocks.
Personally, it feels too slow for me to look for the right block, click and drag the block into the right position. Not to mention it is very slow to "type" a long math expressions and it's easy to make mistakes when there's no parentheses to slightly organize the math.
(I know there's a mod called the Vizzy Builder but built-in code editor would be nice.)

Edit: I was literally trying to learn how to create a Vizzy mod so I could make a block that parse a math expression. Turns out that's what the Funk block does, I had no idea lol. Writing math expressions will be much more bearable with this Funk block.
