Keep user on feature flag page after changes are saved

Proposal

I'd like to propose that users can be kept on the feature flag page that they've modified rather than be redirected to the list of feature flags after changes are saved.

Problem

In my user flow, I'm often only temporarily changing the value of a feature flag. For example, for verifying behavior on staging, I'll enable a flag and then disable it after a few minutes once the behavior is verified. It's incredibly tedious to have to find the feature flag again in the larger list of flags, since I'm always unsure if hitting the back button will revert the feature flag modification I've made.

Additionally, if I want to check that the correct environment was added (checking if I made a typo for example), I also have to dig through the list again to find the flag.

Result

I've attached a proof of concept MR that would instead display an alert on the individual feature flag page that notifies the user of either success or failure conditions.
