What do you want to be added or improved?

As a user I want to ability to add more icons to category, and also change the color as i would prefer more categories. The colors are limited and as a user i think users can easily use the feature to change colors according to their taste. This feature will enhance the visual customization options for users, allowing them to personalize their experience based on preferences. This feature aligns with the growing trend of providing users with more control over their interface.

Why do you need it?

• Visual Organization: Custom icons and colors can aid in visual organization, making it easier for users to distinguish between different categories or sections at a glance. This can enhance overall usability and efficiency, especially in applications with complex data or multiple sections.
• User Personalization: Users appreciate the ability to personalize their experience. Allowing them to choose custom icons and colors for categories lets them tailor the interface to their preferences, creating a more engaging and user-friendly environment.
• Increased User Satisfaction: Features that allow users to customize their experience often lead to higher satisfaction levels. Users feel more in control of their environment, and this can positively impact their perception of the application.

How do you imagine it?

Well I have no programming background. As i have seen this in other apps like, they also let users add icons by have contributing guidelines for icons as an svg's and use json file to implement custom icons in app (I am up for the task.). And also make sure the icons are colored and have some standard size add the details to the contributing guidelines and lets users add the icons for you guys. and for the color part there should be a background color selector for icons apart from default colors.
