Deskpins is a free tool for Windows that gives you the means to have one or more windows in constant view on the desktop, so that it is possible to access them as quickly as possible.
The way it works is quite simple. It is very similar to the action of putting tabs on a page. Clicking on the icon of the system tray, you 'grab the tab'. Once you have it, you just click on the title bar of the window you want to fix in place to place the tab.
In this way, Deskpins becomes, thanks to its ease of use and simplicity, very useful to those of us who often work with a large quantity of open windows.
