I've been using Ubuntu Touch for several days and overall .... great ! One thing I'd like to put forward to consider is moving the whole sidebar from bottom to top and all the core apps would follow underneath. Meaning ... the Ubuntu logo or Scope would start at the top of the sidebar. Similarly like it is on desktop. I know that's rather cosmetic thing but implemention should be relatively easy.
@markalexa I feel confident that it doesn't do it at the moment, but I wonder if the UT Tweak Tool app could make it an option in the future... You could file a suggestion.
In the proposed configuration, using the phone with one hand would be less comfortable, I believe.
