It's a shame that the Sublime package ecosystem seems to be a shell of its former self, with once-popular packages going unmaintained or entirely deleted.
Sublime is one of the few closed-source proprietary programs that I've been more than happy to pay for, just because it's that good.
Sublime was a victim of it's own success when it came to it's packages. It was a great ecosystem, but Sublime needed a complete rework to support some more basic customization, like allowing packages to add functionality to the sidebar.
I wonder whether it would be feasible to create some limited but advanced enough standard for editor-packages which could be used with all editors. Similar to the LSP oder webExtensions that browsers have. I mean a good part of editor packages are probably quite simple and could be generalized enough to work with all mature editors.
Textmate-Package-Format for some time seems to serve that area, but somehow it died out.
