Scroll Anchor - Smart Scroll Positions

About

A Chrome extension that allows you to save scroll positions on any site - including SPA sites (React, Vue, Angular) that have several separate scroll areas.

## The problem the extension solves

Existing extensions like Scroll Button only save the scroll position of the main page (`window.scrollY`). This does not work on:
- SPA sites where the scroll is inside an inner `div` and not in the `body`
- Sites with several scroll areas (e.g. sidebar + main content)
- Modern applications that use `overflow: auto` on containers

## How it works

1. **Select a scroll element** - Enter selection mode, hover over the area where you want to save positions, and the extension automatically identifies (by walking up the DOM tree) the closest element that has scrolling.

2. **Save Current Location** - Scroll to the desired area, click the button, select the relevant scroll element, give it a name and icon.

3. **Jump** - By clicking on the anchor name, the plugin finds the element via the selector we saved and scrolls it (`element.scrollTo`) to the exact location.
