as I was make it more clear...... I should be able to right click in the white space of Sidewise and get an option to add a new group and name it......once I have a named new group folder I should be able to drag tabs into from the main tab bar or at the very least tabs on the sidewise list that are not in a group, or move tabs from one group to another....i.e. the tabs will effectively be subsets of a folder group and I can have as many tabs in a group that I want.
