I wrote in Sublime text since version 1 or 2 and I bought several personal licenses.
I don’t know what to expect from Sublime Text in 2026. ( my license ends in May 2027 )
It is smooth and it has nearly zero issues that affect me.
I can only imagine one thing that could be better in Sublime Text: native Metal support.
We have very powerful technology as A.I.
It may cost less for you to investigate impact of moving to native GPU APIs.
It would be good to know if you have this in backlog.
