FinderMinder allows you to specify where (position) and what size you want newly opened Finder windows to appear. The default Finder behavior is to remember the last position and size for every window, but this can be frustrating if you already know where you want every window to appear (for example, centered at 800x600). FinderMinder must be running for window reposition and resize to take place.
FinderMinder must continue running in the background for window reposition and resize to take place, so click the "Hide" button to dismiss the preferences and keep FinderMinder running. Simply re-launch FinderMinder to access the preferences again or to quit the app.
Pro Cheap and has a free trial
The app costs just $3 and offers a free trial for testing it out before buying.
Pro Has almost all the features needed in a window manager app.
I've tried almost every app on this list, I thought it was amazing of how many there were out there by the time I finally stopped experimenting and searching for the right one I liked most. I chose Optimal Layout mostly cause it was extendable enough and felt lighter while using than the others. There were lighter ones, but those were very limited in their features and customizing.
Pro It's free! Which is fair as it manages only windows for Finder.
Price is right. Comes from a great source of developers who are already have window manager apps on this page's list. I am not sure what they plan to do with this app in the future, whether to keep it light and by itself and work in conjunction with their other window managers or add this feature solely to one of their other fully featured window manager apps.
