If you select Minify Script when exporting, than the plugin does not work and you get a black screen.
It seems to work fine for me when testing export minify (running the html build on a test webserver). Maybe write to support describing the issue if you can't get it to work for you: support.gameanalytics.com/hc/en-us/requests/new
Can you add categories.
General, Facebook, Misc, other etc
I can't see sometimes long actions.
In the lastest version (v1.1.2) there is now categories added.
