Context aware ReacTree?

[AndrewCraswell]

Starting a diagram is a little cumbersome. I have to click the start button, then click to choose a file. The folder that the file picker defaults to is not near the repository I am modifying. I end up taking 15 seconds to hunt down my repo, and select the file I want. However, in most cases I already have the file I want open in the project. Would be much more convenient to be able to right click on a react component and choose "Start Tree", or have the "Start Tree" button just assume that the file I have open already is the initial file, so long as the extension ends in jsx or tsx
