Attention: When installed it may append too much to the clipboard as every change of selected tab results in an append operation.
Use Case: Manually summarizing science papers or PDFs without network connection in hedgedocs.

To enjoy it online host the corresponding backend. Docker will launch locally 2 servers on your PC when you start the compose yaml in the terminal.
* local hedgedocs instance on port 3000
* a python server hosting your pdfs locally on port 8000
The extension will rely on these servers to be running.
Even better ofc if you actually possess a running hedgedocs with friends as you can as well use that. As well a cloud folder should be usable in the same manner as the current localhosted pdf folder.

However my favourite mode is offline Paper reviewing with Cheditor as soon as its done. (For this click the Cherry with the tent :) )
