Better way to make the window disappear

When you press the keybinding to toggle it, it should auto detect if the window is already open and if this is the case it should make the window disappear as it does on ulauncher.

And how can i change theme, i copied a theme to the folder but how can i switch from the default to the theme i copied

I've created a fork that adds a toggling behavior https://github.com/fougner/dlauncher

also, I came from synapse/ulauncher where there's a builtin calc-mode that i thought was missing from dlauncher so i added that as well.
