[Feature] Hide taskbar icon

[Susensio]

I would like to declutter my taskbar from icons that are seldomly used. The funtionality provided by the icon could be presented in the config window.
Besides, if issue #3 gets developed, the icon would become redundant.

Anyhow, thanks for this extension. It's a lifesaver as it is :)

I have added an option to the settings in the version v15
