It would be cool to have a plugins synchronization in ST, the same way Chrome/Chromium do it with bookmarked pages, history, etc...
The workflow would be really simple:
1. Login in ST (Ctrl + Shift + P -> Login -> email/pass)
2. ST checks which plugins are installed and which are not.
3. ST downloads and install all missing plugins
4. Optionally, ST sets account preferences (skin, shortcuts, etc...)
