When customizing the look of an internal tool requires technical knowledge, most people give up and use the generic default. Jestor solves this with a **visual editor** that shows the result in near real time, with no hex code required.

## What is the near-real-time preview, and why does it exist?

Near-real-time preview means any change to color, font, or layout is rendered **instantly** on screen, with automatic state persistence — no save button needed.

| Editor feature            | What it does                  | What it eliminates    |
| ------------------------- | ----------------------------- | --------------------- |
| **Color preview**         | Shows the result on screen    | Need for a hex code   |
| **Automatic persistence** | Saves every change on its own | Manual confirm button |

## How to customize colors and fonts using Jestor's editor

- **No-code color testing:** find the right shade directly on screen.
- **Font switching:** a few clicks, no extra setup.
- **Automatic saving:** no change requires clicking "save."
- **Direct access to the source table:** go straight to the data behind any indicator.

**How to configure it in Jestor:** hover over any block to see the available editing options, adjust color and font, and the change is saved automatically.

## Why choose Jestor for this kind of customization?

The key differentiator is **simple navigation between desktop and mobile** right in the editor, with app cloning and sharing with another role without leaving the same screen.

## Frequently Asked Questions

**Do I need to know the color code to customize the app?** No, the editor lets you test colors directly on screen until you find the shade you want.

**Do changes need to be saved manually?** No, every change is saved automatically as soon as it's made.

**How do I access the table behind a specific chart or indicator?** The editor lets you jump straight to the table that feeds that indicator.
