Virtualpaper has not yet reached stable release. This means that since the development is still in progress, no guarantees are made for the API or the features of the system.
There’s no official demo running, however, the easiest way to setup a demo environment is by using the docker-compose file and the Makefile. More info on installation/docker and starting demo environment.
Feedback is most welcome. If you have any ideas on how to improve or what features would be most benefical to add, feel free to open issue on Github repository. I have built the tool mostly for my own needs, driven by the need minimize the work and cognitive load needed to find the documents. This has lead to all the features that Virtualpaper currently has.
