Working with old php project that contains lots of calls to empty function, array() definitions and what not. The show_definitions is a timesaver quite often, but hovering over e.g. empty or array accidentally will freeze sublime for good 3-5 seconds which is a huge nuisance.
It definitely should have an option to allow to blacklist some keywords.
I have the same issue with the older array syntax and other highly used functions like empty and trim. Depending on the project I have open, the freezes can be 10 or more seconds long. I don’t want to disable the hover popup feature, just block it from attempting to display for the small list of keywords that are causing this issue.
Your case sounds like built-in/core functions, rather than keywords… So show definition of trim takes you to the mid of nowhere, correct?
