Stay On Top

By default, only one window can be in focus at a time. Chances are you always want to have a particular window in plain sight, but your activities keep sending it to the background. On the bright side of things, you can rely on specialized applications like Stay On Top to assign a window to the topmost layer.

Can be used on the go

Since there’s no setup involved, you can see what the application is all about from the moment download is done. It doesn’t put much strain on the computer you use it on, because registry entries are not modified in the process. As such, you can safely carry it on a thumb drive to use whenever necessary.
You might end up scratching your head for a while when the window shows up because of the ambiguous design and approach on the situation. A large panel shows all running processes on your computer based on ID and name. You need to take the time and identify the window of interest to successfully apply the operation.

Leaves much to be desired

Unfortunately, there’s no built-in search function to easily locate a window by name. However, there are a couple of sort options based either on process ID or window name or title. In case you just opened up a window you want to make it stay on top of everything else, it’s also possible to refresh the list, because this isn’t automatically done.
It’s rather painful to go through all running processes, especially since most don’t even have names or titles. Once you do manage to find the one of interest, a double-click operation is all it takes, and the same goes to revert.

To end with

All things considered, we can state that Stay On Top comes with good intentions, but the overall process of identifying the window of interest and applying the process is way too time-consuming. There’s no search option to help with this process, having a huge impact on overall practicality.
