Sublime is missing support for vim actions when used in combination with / or ?
For example:
d/abc (i.e. delete forward until the text 'abc')
or c/abc (i.e. change the text going forward until the text 'abc')
I can workaround most of the missing functionality, but this one is a deal breaker for me. Unfortunately since / just uses the built-in Find feature in Sublime, fixing this is probably non-trivial.
