Thought to provide some feedback on this.
On large CSS files (7000 lines for an example), typing in new code is veery slow with this plug-in enabled.
Tried this on both OSX and Windows 7 and it behaves the same on both platforms, even on powerful systems.
Is this checking for the matching tags at each key-stroke ?
Just wondering which would be the best patch for this behavior, such that other users can use it without any blockers.
Let me know your thoughts on this.
