When I open several application simultaneously, there is necessity to switch between one application to another. But when I place mouse pointer on top of window of some application, then window of other application will close immediately. I need to maintain some window always on top whether I place mouse pointer on it or not.
In Windows, I can doing this with turbo TOP, but I can not discover the same way to doing this in Linux, especially in Linux Mint.
Always on Top
