I love Parallels Tools Box, I have dropped few third party utilities for this little gem. Please provide Hazel like feature set here for File Management.. As this is always running in the back ground. It will be the best add on which is already a best one.
As a part of Parallels Toolbox 5.0, we have added a tool Focus on App that is does exactly this: highlights an active window and dims the rest!
Almost perfect, but it would be preferable to allow toggling with the shortcut rather than two steps process.
I would love to see the option to select a non-focused window to NOT dim. E.g., a Safari window playing YT videos while I work on other tasks. Otherwise, this is a great tool!
I love this tool, but find it quite jarring when I move my mouse over part of the active window and a tooltip pops up and takes focus. I don't believe tooltips from an active application should take focus. It would be excellent if you could stop mouse overs from stealing focus, or at least have an option to.
