Storybook
The UI component explorer, develop, document, & test React, Vue, etc.
Storybook is an open-source tool for building UI components and pages in isolation. It streamlines UI development, testing, and documentation. Storybook provides a sandbox to build UIs in isolation so you can develop hard-to-reach states and edge cases. Implement components and pages without needing to fuss with data, APIs, or business logic. Render components in key states that are tricky to reproduce in an app. Save use cases as stories in plain JavaScript to revisit during development, testing, and QA. Use addons to customize your workflow, automate testing, and integrate with your favorite tools. Stories are a pragmatic, reproducible way to keep track of UI edge cases. Write stories once then reuse them to power automated tests. Whenever you write a story you get a handy test case. Quickly browse stories to make sure your UI looks right. Pinpoint UI changes down to the pixel by comparing image snapshots of stories. -

Termux Desktop
Setup A Beautiful Desktop/GUI In Termux
Termux Desktop is a collection of dotfiles and scripts for setting up a graphical Linux-style desktop environment inside Termux on Android. It helps users turn a phone or tablet into a more complete desktop-like workspace without needing root access. The setup uses VNC so the desktop can be opened through a VNC client after installation. It includes an Openbox-based environment with visual themes, menus, app launchers, terminal tools, file management, browser access, and system applets. The project is especially useful for experimenting with coding, Linux tools, classic applications, and lightweight desktop workflows on Android hardware. Since the repository is archived and marked as unmaintained, it is best treated as a legacy reference setup rather than an actively supported Termux desktop solution. -

AHBottomNavigation
Library to reproduce the behavior of the Bottom Navigation guidelines
Library to implement the Bottom Navigation component from Material Design guidelines (minSdkVersion=14). Bottom navigation bars display three to five destinations at the bottom of a screen. Each destination is represented by an icon and an optional text label. When a bottom navigation icon is tapped, the user is taken to the top-level navigation destination associated with that icon. The bottom navigation bar is easy to reach on a handheld mobile device. When used, the bottom navigation bar appears at the bottom of every screen. Bottom navigation bar destinations should be of equal importance. Combining bottom navigation and tabs may cause confusion, as their relationship to the content may be unclear. Tabs share a common subject, whereas bottom navigation destinations are top-level and disconnected from each other.
