Aquasnap can do the snapping, and more. If any of the 'more' bothers you — like "shake for always-on-top" activating too easily, you can adjust or disable that bit. Hmm, I should add that to my current Win10 machine. I did eventually get a license, so it won't complain about having more than one monitor.
Voidtools Everything can be configured as a search-to-launch tool, but I mainly use it for its blindingly fast NTFS searching. Where Windows Search typic'ly excludes large sections of your drives, eats CPU cycles while it 'indexes', and then still either gives you "Please wait…" or simply claims that it can't find anything, VE just works. Even does NTFS drives across the network (though it has to rebuild a local index of the remote media periodic'ly).
