Hi!
This extensions is every day better, buit I still really miss some pretty basic features in daily use in order to not need to open sqldeveloper anymore:
Tree connection navigation:
Support organize connections by folder. And allow to disconnect all of them by right clicking in the folder -> disconnect
Support double click. Double click in a table -> open and view its data, Double click in package spec -> open package spec, double click in package body -> open package body etc.
