Some fonts such as Fira Code include ligatures for commonly used multi-character programming signs and symbols. When appropriately used, such ligatures can greatly improve the readability of your codes.
When you want to use a TrueType font with programming ligatures, simply install it as a regular Windows font and select it from Token2Shell/MD. If you just want to use the font for a specific server, create an address book entry for the server and change its font settings.
Please note that if Token2Shell/MD was already running while installing fonts, you need to restart Token2Shell/MD in order to properly use the newly installed fonts from the app.
