Hide icon in notification area

[sqqqs]

The icon has no function. Add options in the settings to hide it.

Unfortunately no. The icon is the only way to quit QuickLook.
Moreover, even if there is an option in Settings, hiding icon means no way to get to it.

All settings can be done in the pop-up windows. There add an option to exit the QuickLook.

I don't think it is a good idea. First, all buttons here are related to the current file, but a Settings button, clearly, is not. Moreover, I wonder how many people will change settings so frequently that they see a head-up button during every previewing.

I will not add the "hide icon" function since Windows has already provided a way to hide useless try icons:

Still a good news: you can make your own QuickLook because it is open-sourced!
I believe the icon can be removed by adding one line of code at https://github.com/xupefei/QuickLook/blob/master/QuickLook/TrayIconManager.cs#L62:

_icon.Visible = false;
