I disagree about the opinion of elfbuddy96, when it comes to compare MOVES with ModMove. This app is much better, beside allowing to change the modification key, which is very important for those having a lot of apps running in the background with their own hotkeys (modifiers), MOVES allow you to include or exclude the functionality with specific applications. It has a nice user interface, where you have the option to check or change things. Additionally, the ability to bring windows to front by hovering over it, is great. I was looking for this, as well as many other Mac users, who missed that functionality in an discontinued Mac app, which was used to be called ZOOOM (with 3 O's), which is used to be more expensive than 10 USD. I guess this software is wonderful. Just give it a trial.
