Documentation sorting

# Feature request

## Summary

The docs navigation has been arranged in alphabetical order.
Pro: skimming for the topic is easier.
Con: Doesn't provide the flow of the original documentation; some documentations are best read in order since some topic(s) link to another. An example is React documentation (if I am not wrong).

Solution 1:
In the docs navigation, I think the docs should be sorted alphabetically while their headings/topics/links should be sorted as-is in the original documentation for continuous flow.

Solution 2:
Please provide a sorting mechanism (switch) either as-is from the source doc for those who prefer continuous flow or alphabetically to those who prefer alphabetical order.

N/B: This is my opinion

首先检查 issue 中链接的文档导航实现和 README 愿景。将当前的字母顺序与原始文档顺序进行比较，然后明确预期结果是保留源顺序、提供由用户控制的切换开关，还是采用其他设计；完成标准应包括已达成共识的行为和支持该行为的测试。
