Allow retrying failed validations and deployments
I'm often running into the situation where the validation failed either due to transient circumstances in the org, or due to the org settings being incorrectly configured. In this scenario, I would like to simply retry the validation using the same package, and I'd look for that option somewhere here:
Running a new comparison (using the "clone package" option) is unnecessary, takes a lot of time. Also using the "view comparison" option is overkill. I would rather not go through those motions of recalling the comparison results from cache, going through the analysis once again, etc. Because I know those steps to be unnecessary.
Instead, it would be super convenient with a retry button on the "validated packages" page, that simply runs the validation again using the saved package.
The same goes for failed deployments. Sometimes things do fail due to transient/temporary issues, or incorrectly configured org settings etc, in which case it makes most sense to retry using the same package.
