Simple Alignment
This extension allows you to align multiple selections into columns. It is strongly inspired by the Alignment extension for Sublime Text.
Unlike other extensions for VS Code like Alignment and Better Align, this one does not decide for you what and how to align, and lets you have everything under control.
The functionality is available via the Command Palette (Ctrl+Shift+P > "Align") or a keybinding Ctrl+Alt+A. You can always change the keybinding via Ctrl+Shift+P > "Preferences: Open Keyboard Shortcuts".
Note: This extension requires using multiple selections / cursors. If you are not familiar with this concept, Basic Editing docs is a good place to start.
You can find this extension both in the Visual Studio Marketplace and in the Open VSX Registry.
