This section details on the original issue you should resolve

<issue_title>Option to show taskbar when FL is invoked</issue_title>
<issue_description>Is your feature request related to a problem? Please describe.

I'm used to pressing the Win key to also show my taskbar. Useful for switching from a borderless fullscreen app/game or just to check taskbar items, notifications, time etc. FL does not offer any option or plugin that does this.

Describe the solution you'd like

I'd love to have an option that allows the user to automatically show the taskbar when FL is invoked. Similar to when using the Win key to open the Windows start menu.

Describe alternatives you've considered

With the Win Hotkey plugin I'm able to invoke Flow Launcher with the Win key (duh), obviously this doesn't show the taskbar.

Fixed in commit 7c28dff. The file was missing the closing braces for the class and namespace at the end.

@copilot Please change the wording from "invoke" to "open"

@copilot Please change the wording from "invoke" to "open"

Changed wording from "invoked" to "opened" in commit bb731bc. The setting now reads "Show taskbar when Flow Launcher is opened".

Show taskbar when Flow is opened

Tested

• Taskbar shows up when Flow is opened
• Taskbar hides when Flow is closed
• I suppose that it won't work on a dual monitor setup but I can't test it.
