Move or resize with the keyboard, add transparency or hide from AltTab, using Gridy
Gridy can prove an extremely useful little tool, beyond of adding this invisible grid to Windows, so that any window you move or resize is snapped to it.
Gridy lets you apply these changes to any window or dialog:
Make window semi-transparent; Hide the window’s Alt-Tab icon; Set window to be Always on Top; Resize to a predefined size of your choice; Minimize all windows but the active one.
Note that Gridy does not write anything to the registry, it a standalone non intrusive and super light application.
