Feature Request: dynamically change player window-size

[peter53444]

Hey, First off, thank you so much for this great project!

While working with some casts, I encountered cases where the terminal window size was significantly smaller than expected. This might be due to older recordings, legacy versions, or possibly some post-processing my own tooling performs on the casts. Regardless of the cause, the result is that playback appears visually compressed — especially noticeable in recordings involving tmux or similar setups.

Here’s an example of such a cast for reference:

This is how the cast looks like after altering the window size to what it should be:

Feature Idea:
Would it be possible to support interactive resizing of the player window during playback? For example:

Ctrl + Mouse Wheel to resize the terminal dynamically

Ctrl+"+" / Ctrl+"-" keyboard shortcuts to zoom in/out

A reset control to return to the original size as defined by the cast metadata

This would not only help address the issue above but would also be a great usability feature in general — allowing users to adjust the view as needed for readability or presentation.

Let me know your thoughts, and whether this would fit into the project's goals. I'd be happy to provide more context or help test if needed.

Thanks again!
