Q1. Every time i use "quick trim" to remove lines but it is inconvenient that i need to click the icon once again after removing one line. How can it be easier?

• Normally, we just "single-click" a icon of a taskbar to use a certain command. After the command is complete, the icon will be off automatically. However, if we "double-click" the icon, it remain activated until we click it again. This can help us trim the lines continuously.
