IDE Settings Synchronization
Sharing IntelliJ IDEA configuration settings makes configuring new IDE set-ups a breeze. Just create a JetBrains Account, log on to a dedicated JetBrains server at IntelliJ IDEA startup, and the settings will be synched with the server and applied automatically.
The IDEA server lets you share virtually all of the IDE and project settings, with the exception of some platform-specific ones and those containing local paths. Your code style settings — the keymap, fonts and colors scheme, inspection profiles, and other settings — are available no matter where you start IntelliJ IDEA.
