Sort your ABEM classes in your HTML by a customizable order.
Press Ctrl + Alt + P to open your Command Palette and look for Sort HTML Classes (ABEM Sorter)
abem-sorter.sortOrder takes an array of prefixes to sort by.
By default it looks like this:
"abem-sorter.sortOrder": [
"lp", "x", "o", "c", "u"
]
you can edit the array to fit your preferences in your settings.json file
none so far, but please let me know if you find any :)
Enjoy!
