For what it's worth, I recommend NOT using the desktop build of C3.
I was in the same mindset of "Nah, no browser". The desktop build had a critical issue sometimes, where it would randomly close (even if you haven't saved), and I lost huge amounts of work/time. Sometimes these crashes would then force you to clear your appdata folder for C3, thus spending time logging back in, installing addons/themes/setting preferences... Only for it to crash again randomly and repeat the same steps.
Chrome, with no browser extensions, has been very reliable over the past 4 years!
