I don’t know if this deserves a topic but today I noticed an update in ST docs which describes a new feature about minihtml. Plugin devs who use popups and phantoms can hopefully benefit.
You can check it under “Predefined Classes” header on http://www.sublimetext.com/docs/3/minihtml.html
And the docs diff in my unofficial repo: https://github.com/maliayas/SublimeText_Documentation/commit/cdaa2fd8d1f180a491cb7bfaf76868cded420313#diff-ebce555920cae668e23e1b2395470cdaR167
