After finding Even Better TOML was eating all the memory in VS Code and that it is no longer maintained, I found an improved linter and formatter in Tombi.
It integrates with lots of editors and as a standalone tool with useful schema auto-complete and validation. I've found it fits in well with a Python ecosystem.
Best of all the author is really quick to respond to issues.
I agree however you forgot to mention the excellent Geany, which looks more comparable, and I think it be better for a developer to spend time improving that rather than porting a heavily MacOS based editor.
I find it strange that more people have not brought up the 'lost-sale' fallacy. By saying 'no' he actually loses out in the end because if the magazine is only looking for free photos, say to the keep costs down, it will just go elsewhere and the readership of that magazine will probably never know about that amazing photograph nor the photographer himself.
That argument is only bullet-proof when all magazines are in exactly that position. But some magazines may well just want to use that picture and try to press the cost of using it.
