As a software coder, i use code block a lot. So it will be great if the code block can be improved in the following ways 1) Include numberings 2) Ability to change font. The current font is quite ugly 3) A tiny "copy code" button at specific corner 4) Ability to add a caption (top or bottom) to allow us to briefly describe the code 5) For the language, include powershell, java properties and mermaid language. 6) For mermaid language, perhaps can do similar to what notion does, show the rendered charts as well. One thing i like about the current code block is that it allow us to change the color for specific selected part of the codes, good for us coder, who wanted to highlight specific part of the code to draw attention.
