Make vertical tab bar detachable / its own "pane"
I'd like to have the tab bar vertically at the left of my dashboard, then 1-2 detached panes, then the grid shows what is selected via the tab bar in the center, then some more detached panes. Currently (with vertical tabs), the tabs need to be right next to the tab-switchable grid pane. This means that either this combined element needs to be at the very left or, if it isn't, dragging and dropping items to detached panes that are on the other side of the tab bar / grid "pane" is very iffy as the tab bar will switch the displayed grid when dragging items over the tab bar.
