Personally, even if I type in lowercase letters, I want code completion candidates that start with uppercase letters to be displayed, so this time I will introduce a method to achieve this.

By default, Match case is checked and First letter only is selected, so the first letter is case-sensitive and candidates are displayed.

By unchecking Match case, case sensitivity is disabled, so even if you do not enter uppercase letters at the beginning as shown in the image below, names with uppercase letters such as class names are used as code completion candidates. You can display it.
