GrabbyWindow 2.5 for Mac was free to download from our application library. The program lies within System Tools, more precisely File Managers.
From the developer:
GrabbyWindow™ provides a full featured file browser right inside every application. This kind of integration gives you faster and easier access to files and avoids endless import dialogs or annoying switches to the finder during e.g. layout processes.
GrabbyWindow™ also offers better control over files.
