Feature request: custom filter for trace stack

[EnixCoda]

The trace feature is really powerful and helpful. I hope this could make it even better.

For example, I'd like to exclude stack trace of node_modules dependencies like redux-thunk so that I could focus on my source code.

Perhaps the UI change could be like

1. In the settings tab, add a list of text inputs for excluded paths.
2. In the trace tab, add a exclude button right next to each stack. So that users could exclude specific paths by one click.
