A peak at how SEM looks in a sidebar ;)
Scheduled to be added proper into the main SEM entry when Opera 29 goes stable. So ultimately there will be only 1 SEM entry in the Opera Addon Store in the end.
A lot of problems pop up when a popup becomes a sidebar like how the resizeable height and width messes with the layout and how updates have to become real time as a sidebar does not disappear after an action.
Tried to touch the main code as little as possible in order to maintain the same code for both Chrome and Opera builds.
I'll also like to thank the Opera moderators, dmichnowicz and for_d, for answering my questions pertaining to the publishing and visibility of sidebar extensions.
