Really miss Divvy (RIP). At the risk of causing a good thread on Apple's weird inability to lauch a really valuable OS feature devolve into a list of workarounds, Hammerspoon (a generic automation tool) plus this script (https://gist.github.com/artburkart/15b62f1a741eef0f74492860a...) offer a really good equivalent, with the added ability to change hotkeys, extend behaviour, modify behaviour, etc. since it's just a script. I was devastated for a brief while when Divvy (and then ShiftIt) stopped working, but haven't looked back for a while.
