Completely useless for the past 20 years. I have it always hidden with 0 loss of functionality.
It provides no info about what windows are open, it does random things when you click on an icon, it has an indicator that tells you that an app is in memory but may or may not have a window. And all these become even worse once you have multiple monitors / spaces.
Just copy whatever gnome/kde/windows are doing. All of these have figured it out. Only macOS needs an investment of like $50 per year in helper apps to deal with the poor app and window management.
