Compare Flow Versions within the same Org #1050
Description
Describe the problem you are trying to solve
The "Compare Metadata" feature is great for comparing Flows between two different orgs, however it is currently unable to compare Flow versions against itself in the same org. It would be a wonderful upgrade to be able to compare Flow versions within the same org because people don't always document what they change between versions.
Describe the solution you'd like
When Flow is selected on the Compare Metadata screen, after Continuing, selecting a Flow, then clicking "View or Compare Selected Items" it would be perfect if there was an option in the org selection to choose the current org. And then if the current org is selected an option could appear to select the Flow version for the comparison.
It would be a huge bonus if we could also select the version on both sides of the comparison, so it doesn't always need to be compared with the currently active version.
Thank you for creating such an amazing tool!
