Good idea, bad implemented. I searched for a possibility to be able to move different tabs I opened related to a specific topic into the background while I am working on other topics. This add-on can manage this simple task but at the cost of overcomplexity and sloppy implementation. The settings are horrible many and poor documented, so you have to try a lot - risking the loss of your tabs. On the other hand, some settings I would except are not there, i.e. you cannot choose the location of the auto-backup by yourself. Actually I do not want any program to just save some files into a given folder on my workspace, I want to decide on that.
