When I work on windows, I just use cygwin with the mintty shell to get productive with a familiar look&feel. What am I missing with this setup that Wish fills?
A lot of Windows users (like myself) are somewhat committed to tools like Powershell in addition to Cygwin. I currently keep both Git Bash and Powershell open so I can switch back and forth as needed. Wish allows me to switch between these seemlessly with a common set of features across both.
