Could you add the ability to add a string to RichTextBox?
Now you need to follow these steps:
1. Get Text
2. Add New Line (\n)
3. Add string
4. Set Text
First, it will be easier. Secondly, if the project runs for a long time and the log is large, then the program has to operate with large volumes of lines. (Imagine if the log contains 1000 rows?)
