Hello I bought the app through the App Store and installed it on my Macbook (Mojave 10.14.3 (18D109), Safari 12.0.3 (14606.4.5)) but when I try to save the current tabs/session nothing happens. Can't change a name/title. Suppose normally you should see a list with the sessions saved?

Also I understood that I could save sessions and add tabs to. it . So was wondering if I just could make an empty session and add tabs to it that would be great.
