Logos used to have a feature on the panel menus - or perhaps, on the panel toolbars - that was called "Parallel Resouces." I believe it may have even been represented by a button featuring two parallel lines. The benefit of the feature was that, if for example, I were consulting one particular systematic theology resource and wanted to consult another, I could click on "Parallel Resouces" and it would give me numerous other systematic theology options and choices. In the current version of Logos (I have 8.11.0.0017), I no longer see the feature, 'Parallel Resources.' Grateful for any help.
