Steps to reproduce

1) run "vue ui" 2) create an empty project (without starter content) and "default preset" 3) in project manager, click on "tasks" -> "serve" -> "parameters", then click save to close. 4) click on "plugins" -> "add plugin"

What is expected?

I expect I'm supposed to see a list of plugins I can install.

What is actually happening?

I see the same configuration parameters that was in the tasks->serve->parameters page. I am unable to select "search" or "files changed" tabs (no response).

This is my first <5 minute foray into vue.js, hopefully this is just a minor bug.
