It is a fantastic idea, expecting next version could be better

It is really a nice idea to provide us this sort of applications.
There are some personal suggestions:
1. If there could be a sidebar could show the info of the art works ( artist, year, type, location) permanently.
2. It seems that when different collections were opened, they were opened in different windows.
3. If the timeline of each collection could also be showed in sidebar or somewhere else.
