Sublime Text 4 Half step font size adjustment Plugin

As outlined here, Sublime Text's font-size setting uses points instead of pixels. As a result, in many cases, especially with non-standard fonts (but this is also true for default fonts like Consolas), you might need to use decimal values like 9.5 instead of rounded point amounts.

This plugin doesn't convert points to pixels, but it allows you to adjust the font size with the default keybindings by half a point for finer real-time control over your editing environment. It replaces the default Sublime Text keyboard and mouse bindings (i.e., Ctrl + "+" and Ctrl + "-" as well as Mouse Scroll Wheel) to change the font size by 0.5 of a point instead of the default 1 point.

When you change the font size with hotkeys/mouse wheel, the status bar displays the new font size value.

Installation

1. Clone this repository or download the ZIP file.
2. Place the extracted folder in your Sublime Text "Packages" directory. You can find the "Packages" directory by going to Preferences > Browse Packages within Sublime Text.
