Is it possible to centralize them and get the proper order?

[samit4me]

Yes I know what you mean, it doesn't look great. I don't know of any other way but that doesn't mean you can't. Will have another look when I get some more time.

[coryhouse]

I agree centralizing would be preferable if possible, but this reads clearly as is, so I'm good w/ merging as is if @kwelch and @nickytonline are.

[nickytonline]

I'm fine with it as is. 👍

[kwelch]

I pulled this locally to try it out and got runtime errors with the production build.

Uncaught Error: Module build failed: Error: Unexpected extra options ["react","stage-1"] passed to preset.

Dev environment appears to be running properly.

Validated by changing SavingsForm to use arrow functions and static propTypes.

AppVeyor died for a peerDep, but I don't see any issues with merging.

Great pickup @kwelch, thank you for finding that issue ✨
