Once we do changes in the files out of IntelliJ, the changes are shown in the ide.log
However, the editor doesn't reread these files, unless we asked for it explicitly by clicking the Synchronize button.
1. Is this the normal behaviour? I expect that once the editor gets the events, it will refresh automatically.
2. If this indeed the designed behaviour, does synchronize scan only the changed files, or go over all the files in the project?
3. How can we tell when synchronize has finished?
