After installation of the plugin everything seems to work, but if I try to add a row in the configuration dialog, an additional row is added and the "Loading..." message appears and never dissappears. I can move away from the menu by clicking anywhere, but cannot save the configuration. It is not possible to add another row and thus I cannot use the plugin.
That's really a pity b/c I like the idea and I also use some other plugins by you. The user Kube seems to have the same experience. Could you have a look? If so do you require any further information than the one given below?
