Quick Repeat of Failed Tests

[Chiramisu]

In an effort to increase my speed and accuracy I'm using a min accuracy and weakspot from the funbox and would like to be able to quickly repeat the previously failed test, or optionally to toggle the quick restart to instead quick repeat a failed test.

If this would not be a priority for the maintainers, then would someone at least be willing to look at my PR if I added this feature? In that case, I've identified the following relevant source files, but given my unfamiliarity with the codebase and inexperience in Node and TypeScript, I may have missed some, but I'm willing to learn. 😀

frontend/src/html/pages/settings.html
frontend/src/ts/config.ts
frontend/src/ts/controllers/input-controller.ts
frontend/src/ts/pages/settings.ts
packages/contracts/src/schemas/configs.ts

May be related to #2627, but I'm requesting a slightly different implementation and willing to help.

I am looking for a repeat keyboard shortcut also. Looking to practice the same test a few times without having to use the mouse.

Would be nice just to have single key shortcuts on the test result screen. Keys don't do anything. Instead, just have n for next, r for repeat, for example.
