I just downloaded nw.js normal v0.19.3 and I see that the manifest option "toolbar" is no longer supported. It says that F12 should bring up the dev tools but it's not working. I'm using a mackbook BUT I'm booted into Win 8. Any idea on how I can see the dev tools?
You need to download SDK version of NWJS instead of Normal version, as Normal version doesn't have dev tools
After downloading SDK version
