Waybar, Monitor per workspace and shortcuts

[Lure5134]

1. Is there any shortcut to toggle waybar globally? Not like fullscreen on one monitor but on all?
   And can I change waybar to be hidden by default?

2. Can I set the workspaces per monitor?
   For example that workspace 1 is always on monitor 1, workspace 2-3 are on monitor 2 and workspace 4 is on monitor 3?
   I have seen the option in the settings under "Appearance" -> "Per-monitor workspaces". But when used I am not able to move an app via shortcuts from monitor 1 to 2.

3. When pressing SUPER + K the terminal opens. I don't have a shortcut for that (I use the default SUPER + Return)
   I want SUPER + K to be used for the keybindings. But it still opens the terminal.
   The keybindings dialog is too always on top. If it is opened and after that the settings dialog get's opend it isn't visible but behind the keybindings dialog.

1. There's no waybar, and also no you cannot hide the bar
2. You can make custom keybind that moves app to different monitor
3. Super+K is reserved keybind for cases when hypryou crashed, because Super+Return uses IPC, so if hypryou crashes Super+Return doesn't do anything. And you cannot remove it (unless you touch main hyprland config)
