Hi @Friendly-Banana,

Thanks for this PR, however, I am going to close it for three reasons:

• There is already a way to construct a custom AttributionWidget - it doesn't create any of the UI for you, but it's not too hard to copy from the current implementation if necessary
• This method of implementation creates a lot of code duplication - if it were to be accepted, it would be better to just have an argument to disable/remove the default text
• Improve Attributions #1390 should be on the way relativley soon - we are still in discussion on the Discord server (note that it may or may not become a plugin: we are still undecided, and it will depend on the extent to which the PR goes). Whilst it won't replace this current method of attribution, it should resolve the issues you mentioned in your original issue ([FEATURE] new AttributionWidget without default text #1392).

Please don't be dissuaded from contributing in the future: we are always happy to have new ideas and PRs! Once again, many thanks for your PR!

H @JaffaKetchup,
Ok, I understand. Looking forward to #1390.
