Can Obsidian add floating parking function? Auto hide and show
I do training.
I often use Obsidian as an auxiliary presentation for my courses.
Sometimes, we don’t need to frequently switch program windows.
Hope to hide Obsidian when not in use, in the form of a floating small window; When needed, hover over the mouse to display it.
If there were transitional effects and shortcut keys, it would be perfect.
Also, can we set the option to minimize Obsidian when it is turned off, rather than exiting?
thank you.

You might look at window management apps — some may have options that let you control Obsidian’s window in the way you want.

I have tried some hidden display tools, but they are all too rigid and the effect is not very good.
If the Obsidian could have this feature, it would be perfect.
