Notation GUI alongside initial labeling GUI

[psomers3]

Would be cool if there was an option to bring up the video playing/notes GUI during labeling. But this would be interesting to do "correctly" so the tool stays usable with images that don't come from videos. Maybe the only good solution is that the two different apps are launched separately. Can the database be accessed from different processes?

The database should be accessible from two different processes. One could also save the intermediate state of the labeling tool to the disk as a temporary file and then retrieve from there (might be possible)
