I too was surprised to find no proxy settings, in fact I was surprised that there is pretty much no ability to configure the browser settings at all. What about privacy settings etc? If it's a chromium wrapper then we should be able to configure the chromium instance used. chrome://settings pops a blank page.
This is not really an answer, we will have to get one from a Windows person. But just FWIW, in OSX Terminal is an app that is standard on the Mac. Mac is all about GUI interface which is nice. But it is also based on Unix and using Terminal with bash commands can do a great deal of things and can even be destructive to the uninitiated.
I am not afraid to use Terminal commands when following someone’s instructions but I generally keep it as a big tool I only get out when absolutely necessary. I can see there are programmers using Freeter. To them it probably makes better sense using commands. For my use it is something that if I had the option in preferences I would probably just do away with (hide). And yes, that is because I don't really understand it's usefulness of command lines in a day to day workflow.
My work is all about organizing and staying organized as I try my best not to get totally lost in a project. Of course, I am always willing and interested to learn more. To me it is all about keeping all the parts together, building a plan, and staying focused.
