Currently I have a panel, that is very wide and is vertical. It basically works as a sidebar.

Of course, it is set to auto-hide, because otherwise half of my screen is under this specific panel. But I feel like it gets triggered a bit too quickly. It's a bit too sensitive. I'd like to be forced to keep my mouse completely in the corner for half a second for it to show up. Or even better, ONLY show up with a keybind. Any way to do this?

I'm on openSUSE tumbleweed, freshly upgraded, so I assume it's the newest possible KDE version( 5.19.4)
