Code browser idea [Feature request]

Hello,

When I browsing reposities I checking into files like as text/code/xml etc but each click to any file means creating whole page…
I would prefer to click a file on the left/right side of the browser and reload only the code area like as visualstudio code does.
Another idea is file sizes of the project files; I would like to see size of the files in the repo like as file browsers does.

Thanks in advance

fortunately, there is github.dev, exactly as you wish

when you are at the root of the repo, just press the dot key . or change the URL, for example mine is,

https://github.com/jdevstatic/lightweight-web-server

just change com to dev
