Con Occasionally freezes
This application occasionally freezes.
Con No highlighting when searching
Doesn't highlight all search result instances.
Con Home and End keys require shift being pressed
Con Occasionally crashes
Working remotely with a full buffer may cause complete terminal app crash.
Con Highly opinionated
JSLint has a very strict, dogmatic ruleset that cannot be changed or warnings turned off. So much so that rarely any code will pass JSLint tests. It's reasonable to evaluate if all warning are worth changing.
Con Difficult to know which rule is causing which error
Since you can't edit the rules and it's not programmed in a way to display the rule that's being broken, it's difficult to understand which rule has been broken.
