Hi, great job at adding the help window!

I have one suggestion, I think it should only be accessible Normal mode, so either during Pause, or before running the test.
Maybe also in the test results screen, but that can be a separate issue.

Guess the description wasn't clear enough, sorry about that.

Hey @radlinskii, I just addressed that in the last 2 commits.

Nice project btw.

[theghostmac]

Just did cargo fmt That should pass the build workflow.

[radlinskii]

the build job run is still failing, let me know if you plan to fix it yourself or not

ref #70

[theghostmac]

I'll fix it. I've seen the issue.

[theghostmac]

Hi @radlinskii I've addressed the issue. Was having a hectic week at work, hence the delay.

1. Changed the render method to take impl FrameWrapperInterface instead of Frame
2. Removed the generic <B: Backend> since we're no longer using the raw Frame
3. Changed direct frame methods to use the FrameWrapperInterface methods
4. Simplified the imports since we don't need Backend anymore

did you even try to run the app with your changes?

There is a runtime error when running the app on your branch, that is kind of hard to miss...

Before you've asked for approval even before the app would compile so I'm assuming you still didn't try to run it, which is kind of disturbing to me.

when help window is rendered then 's' keypress should not start test, or if it did, than the help window should hide.

[theghostmac]

Okay, the most user-friendly one is the econd option -- to automatically hide help when 's' is pressed.

The user can now:

• Toggle help with "?"
• Press 's' to dismiss help and start the test in one action
• Still use 'q' to quit whether help is shown or not

Any other changes required to improve the user experience?
