You should submit that change as a PR. The addon readme states it tracks your roll numbers.
Please don't submit a PR that changes how something has worked for years. Unless it's a cleaner implementation of it.
Even better, allow the user to configure it to show only their own rolls or all rolls.
Now this is fine but it should by default work how it has and have the option to opt in to the change. There are sometimes reasons to not follow this rule.
I agree, backwards compatibility breaks/unexpected changes in functionality are bad - I made the PR suggestion due to the readme technically being inconsistent with what the addon
actually does. But a PR for correcting the readme is probably an easier fix XD
I should have caveated my post with a suggestion to first have a conversation about any changes to addons with people in the Windower Discord, to save you time (and tears) in the long run.
