This is where Always on top comes in handy.
Always on top allows you to set a window to always overlay all other windows.
This means that some apps can do it, and some apps cant.
Fortunately, there are third-party apps that can enable always on top for any window.
One example that we recommend is WindowTop, availablehere.
Tip: The dark mode is purely a colour inverter, so is not a particularly reliable tool.
The transparency feature actually works pretty well with the always-on-top mode.
A slider allows you to configure how transparent the window is.
A checkbox under the slider also allows you to Enable click-through.
Click through allows you to interact with a window underneath the affected window.
Its a very effective combination feature, although it could be annoying if you accidentally enable it.
