Tested it now somewhat. Some points so far:
1. Installation script doesn't work on Windows. Exit 1 is particularly problematic as it kills the current shell
2. No search on current page vim style (/) or full page up/down J/K
3. On Query page j works but k somewhat scrambless the page in Windows terminal
Not sure how seriously you want to support Windows, I could rise tickets on Github
I don't have a way to debug windows, so atm it's kind wysiwyg.
#2 is a great idea. open a ticket if you'd like.
