@wjames111 There seems to be a decent bit of overlap between this PR and the one I'm working on currently: #1438
I'll probably wait for you to finish this to continue

@zweatshirt if you've already done work on this, we can go with yours.

Oh no you're all good! The PR I linked is for making the GoalCalculatorLayout a shared component. There are no improvements apart from breaking it out into a more reusable component. I would be happy to add these changes to the shared component when you're done and it shouldn't take long for me to do. I just wanted to let you know about the PR.

@wjames111 Do you know if you'll continue working on this? If not, I'll finish up #1438

@zweatshirt go for it that would be super helpful.
