提几个小建议（Make a few suggestions）

1. 希望在线打开的代码能够切换分支;
2. 希望能够直接在页面中能够搜索出对应的github项目，然后打开;
3. 希望能够直接编辑这些代码（切换成其它文件时，修改的文件还能保持不变），还能够保存修改的文件（也能导出到本地），意外关闭浏览器还能够恢复相关代码，等等;
4. 希望能够直接在线运行，在3的基础上，能够实时预览效果;
5. 希望第一次进入github1s的时候，如果当前浏览器不存在OAuth Token，能够有提示/指引

English ：
1. Hope that the code opened online can switch branches;
2. We hope to search the corresponding GitHub project in the page directly, and then open it;
3. You want to be able to edit these codes directly (when you switch to other files, the modified files can remain unchanged), save the modified files (you can also export them to local), close the browser accidentally, and recover the relevant codes, etc;
4. Hope to be able to run online directly and preview the effect in real time on the basis of 3;
5. When entering github1s for the first time, if there is no OAuth token in the current browser, there will be prompt / guidance
