A feature which would be great as a cross-platform option within Toolbox under the 'Internet' category is to be able to emulate a particular network speed/quality. Mac OS has a developer settings pane that offers this (see attached screenshots) with variable options to do things like long latency, slower speeds, etc. I have found this useful when testing websites, applications, etc. It may be only good for more advanced users with such needs, but seemed an idea to suggest here for consideration. Again, what I have is just for Mac, but a consistent tool that worked for Mac and Windows would be great.
