Categorization system

[Gobans]

Hi, I think this library's idea is very good and believe could be helpful tools for both of developers and users, and I want contribute this wonderful library.

In order to improve the experience of the voting function of the users, I suggest categorization system, which is able to give more context of feature to users.

For example, developers could classify them into user interface improvements, bug fixes, performance enhancements, and new features.

It's what I think it looks like

When the user selects a category, the functions are filtered according to the selected category.

This will allow users to understand more about the background of the feature and to better classify and view the features they want to see.

What do you think of my idea?
