Saw this referenced on Amibroker forum. Looked it up and might have to tinker with it this weekend. Sure many users here could possibly get good use of it in speeding up daily setup. Easy to get a software to tile and remember but those with large monitors and multiple applications could benefit. Did some reading and hard to find new material. One article seemed to say it had a hard time with multiple monitors while this link below mentions multiple desktops/monitors. https://www.techrepublic.com/article/windows-10-powertoys-how-to-use-and-configure-fancyzones/
Someone else was using with 4K 55" screens, setup screens within the screen, looked good. Haven't tried it, haven't swapped to huge single monitor yet. Sure they'll be around to post it soon.
I use a large 4k TV but see no real use for this . I use a multi desktop app, not the windows native one. Most software can be set up on its own, displaying multiple windows where you want them
