Yeah, I saw this issue. Didn’t investigate on how relevant the open points are for usual end users, that’s why I asked. In other words: The state of the plugin.
Regarding GitHub Copilot and its potential integration with Sublime Text 4, as of now, there has been no official announcement or release of a direct integration for Sublime Text. GitHub Copilot has mainly focused on popular IDEs like Visual Studio Code, JetBrains products (IntelliJ, PyCharm), and Neovim.
However, Sublime Text does have a strong community of developers who might implement workarounds or plugins to bridge this gap. It’s possible that with continued demand, GitHub could expand Copilot’s support to Sublime Text 4 in the future. For now, you might want to keep an eye on Sublime’s community forums or GitHub’s announcements for any updates.
