Hello Codeforces!

I have been working on a small tool for people who use the Zed editor: zch, a terminal dashboard that works with Competitive Companion.

What it does

• Receives problems from Competitive Companion, saves the samples and opens the file in Zed
• Runs all samples with one key, showing input, expected and your output side by side, with the differing characters marked, plus time and memory
• Checks output like a judge: tokens, lines, case-insensitive, floating-point (epsilon) or your own testlib checker
• Runs interactive problems live
• Submits to Codeforces from the same screen and shows the verdict

It is free and open source (MIT), macOS only for now: https://github.com/prsweet/zch

Install with brew install prsweet/tap/zch or cargo install zch.

I would love feedback, bug reports and feature ideas.
