Plug-ins. "The Modeling Store":

* Startup9000 Simulator

* ClassicAutosAsInvestments Simulator

* My Personal Stamp Collection API Plug-in (not-public, not-for-sale)

Basically, theres enough weird stuff out there that could be a component of someone's financial hopes and dreams, that communities could sprout on being able to enhance around a topic.

There's also that first step of needing/wanting to be able to API-into the product to explore the idea to see if it's even something that can be modeled.

Being from the UK, having a plugin layer able to differentiate US from UK implications on finances would be extremely useful. But also as a fellow developer I hate to recommend a level of refactoring that might break you!

have you seen the UK tax template (plan settings > tax) and account types? curious what additional controls / differentiation you'd like to see.

Ah - no :-) I just read the feature list and didn't dig deeper. Just assumed it was going to be US-only. Impressive if not. How do you keep up?

> share a read-only view of your plans

I think this is because you are conflating "model" and "plan"; whereas the conventional use of plan probably means model, when playing in your Sandbox it looks as if "plan" is model+data.

The grandparent poster is describing sharing models.

I think the comments below summed it up well.

Basically setup my own versions of Roth, or other products.

In Canada, TFSA and RRSP are one

Have you seen the TFSA and RRSP account types?

I try to offer as much configurability as I can, but if there are other areas where you'd like to see more of that, definitely let me know.
