Google Analytics Usage
First of all, thank you for providing this useful plug-in. As a developer, I know that it requires a lot of your time and love to do an open source project that offers value to others.

However, I want to report an issue that I see in the source code of other Sketch Plugins too: the use of Google Analytics without consent.

While it seems to be a practice used by many of the popular plugins (e.g., AutomateSkecth -actually I found it there the first time while trying to resolve an issue). It's not a good practice to not ask for user consent in a desktop application. Mainly because the non-technical user doesn't have a way to turn it off easily. 

For users that don't want tracking, I recommend to add `www.google-analytics.com` to the `/etc/host` and point it to `0.0.0.0`; or to use a tool like Little Snitch.

For plugin authors, I think that the transparent approach to analytics used in popular projects like Homebrew: https://docs.brew.sh/Analytics should be an example. Homebrew provides a way to turn off analytics, and makes explicit what information collects and who can access it. They also share a summary of the collected information.

As Sketch evolves towards having more plugins, it will be great if it uses a permission model to sandbox plugin network usage. Otherwise, it becomes risky to install plugins without taking a look at the source code first.
