Check out this fantastic code editor called ZED. I think this may become your new go to, and they have open sourced their software.
Nathan Sobo writes on the ZED blog
We're excited to announce that Zed is now an open source project. The code for Zed itself is available under a copyleft license to ensure any improvements will benefit the entire community (GPL for the editor, AGPL for server-side components). GPUI, the UI framework that powers Zed, is distributed under the Apache 2 license, so that you can use it to build high-performance desktop applications and distribute them under any license you choose.
Let me know on X what you think about it.
