It is categorically not suitable as a way for most users to save changes to their own wikis. The fundamental problem is that browsers are free to "evict" local storage whenever they want, and we get no warning of it. Browsers added this feature to give web developers a way to improve performance through locally caching data pulled from the server. The assumption that the data is volatile data and can be retrieved from the server if it is lost, runs through the implementation. Having said that, local storage can still be very useful, including things like experimentally loading plugins without having to save before reloading. I plan to improve it a bit further, in particular I want to get it working well in the client server configuration so that local storage can be used as a temporary holding area in case the connection to the server is lost.
