Ash HN: what cloudformation tool editor are you using?

TL;DR: looked for a tool, found none, should I create one or is there any I could already use? My common use case for which i don't have a perfect tool is: a. i have tens of active cloudformation stacks b. i want to update a stack c. i want to see (with 100% accuracy): 1. which resources will be updated 2. which resources will be created 3. which resources will be deleted The way i do it now: - have templates versioned on git - execute `aws cloudformation update` and blindly trust that no other changes have been performed between my updates. - (some other tweaks too long to describe here) What tools are you using? I feel like creating one, but i cannot be the first one bumping into this (i might do it wrong - that's also a possibility).
