What features would your all-in-one REI platform have if nothing was missing?

[Megan S.]

I am asking because we spend an awful lot of money on REI platforms and not one of them has everything I need. If anyone else has had this experience, I am really curious:

1) What would your ideal REI analysis app/platform do if it did everything you need?

and/or

2) What does your current tech stack look like?  Which platforms do you use and what do you like about them?

Thank you!
