Let's say I mount a large project on a remote disk via Transmit or Macfusion. So whenever I navigate deeper into the subfolders in side panel, each subfolder takes more time to open. Hell, I can spend 15 to 20 min. waiting for the subfolder to open! But next time things go smoothly. It looks like Sublime text 2 gradually downloads the whole directory structure, and doesn't allow me to open subfolder which it hasn't processed yet.
I suppose it'd be great to have a settings to choose between 'awesome instant search' and 'great performance for huge projects on remote devices', because it's not always convenient to have a clone of the project on local disk
