Customizable UI Options

I would love to have a code development window open on on side of the screen (or even the option to ingrate with cursor) for development, as well as just more themes and fonts to choose from. As a frontend developer myself, I find it useful to make smaller changes to the code in the AI client before I import it into the IDE/production. If anyone has questions feel free to reach out at retrogptxyz@gmail.com - loving t3 so far!
