I'll deploy now an update pending since a few weeks, I've redone the admin pages in a more modern style to make them easier to use on mobile.
I hope there won't be bugs, but it is quite possible that you encounter errors in some case, as I can have missed something.
If you get an error, please describe the exact action you were trying to do, from which page you went, and the address of the page on which you had the error.
