What does it mean to display the subject line in text messages?

The text message display subject bar will have a topic window when the text message is entered, which can be edited. Character counting means that when writing a text message, there will be statistics of the number of entered words at the end, making it easy to control the number of words.

This is mainly for iMessage. When you enable iMessage, open the subject bar, and there will be two lines in your information input box. The first line is the subject, and the following is the text. The number of characters will be counted. Displayed on the right side of the input box, the subject functions almost like an email, and the character count is simple. In order to facilitate checking whether the sent content exceeds the receiver's tolerance.

Theme composition:

The WINDOWS theme determines the visual style of the entire system. Generally, the files in the theme folder should include two parts: one is the .msstyles visual style file, One is the shell folder.

Some only have .msstyles files but no shell folder. If you want to use a third-party theme on the WINDOWS system, you must install the uxtheme.dll patch for the third-party theme on the WINDOWS system and make sure that the Themes service in the system's "Management Tools-Services" is turned on and in an automatic state.
