FocusLn

A VS Code extension that allows you to highlight and manage selected lines in your code through a dedicated sidebar view.

Problem Statement

Developers frequently have to move between different areas of the codebase when working on multiple files, particularly when refactoring or comprehending intricate business logic. It can be annoying and time-consuming to constantly switch between tabs and scroll through lengthy documents. It's simple to forget crucial code segments you were working on, which can reduce output and add to mental strain.

FocusLn addresses this issue by offering a specific sidebar view that facilitates:

• Maintain track of crucial code segments in several files; swiftly move between your main points of interest
• Preserve context without becoming bogged down in tabs and scroll positions
• Effectively arrange your areas for work-in-progress.

Features

• Highlight selected lines with a customizable background
• View all highlighted lines in a dedicated sidebar tree view
• Support for multiple line selections
• Optional persistence of highlighted lines between VS Code sessions
