I'm currently a Windows user but I am looking to transition my main workstation to Linux like my servers. However I often use the Hide Window Hotkey Tool, this tool allows you to select windows to hide then upon pressing a hotkey they are hidden from the task-bar but not closed, they can then be restored with another hotkey. I was wondering if there is an alternate tool for Linux. Or even an API to do such a thing, I'm a software developer and so I just need some guidance.NOTE: This is not minimize, this is hiding the program from the task-bar. 
Does Linux Allow For Hiding Windows?
