Could crossterm be helpful?

Hey, author of crossterm here. Because of some discussion in wg-cli I came up to this crate and saw the issues.

Crossterm solves a lot of issues you've listed . Like input, clearing of screen, coloring, rawscreen, alternate screen etc. It is completely 'Send' and 'Sync' and cross-platform.

I thought you might be interested in it. I am currently working on version 0.5 which will make user API more convenient.

Start by reviewing this issue and the linked crossterm project to understand the proposed terminal capabilities. No files, tests, entry points, or concrete acceptance criteria are named; a maintainer decision is needed before the work can be considered done.
