Monitor UI and Simple UI not compatible with linux

When installing the Monitor UI and Simple UI, I get an error on the dependency 'fsevents'. Reading the 'fsevents' docs, it seems it's platform specific for Mac OS X (darwin). I'm using linux. Here's the terminal output:

It works on Windows and presumably on MAC. These are the high priority platforms and apparently the only ones on which it has been tested. If you choose to add Linux support, please ensure that your changes are tested on Windows and MAC. I would be happy to handle the Windows testing.
