Enable a link in the drop down menu - containing the "Link Sets" options, that will enable linking to "All Open Resources" in one click, instead of manually adding one at a time. E.g. An "All" option, next to the "None" option AND/OR A "Similar" Option next to the "None" or "All" options - to allow for the tagging of all similar resources (by Logos default categorization.)
Enable the ability to change the default template, to a custom template, for/as the default home page passage guide.
Ability to change "Guide" tab icon pictures, like with shortcut icons.
Ability to put an entire series under one tab. For easier, more condensable searching/use 
Ability to program where certain Books, Dictionaries, Bibles, Commentaries, and Tools open when selected, in a prioritization type manner. Both in layout and tab categorization.
Ex. When I click a bible dictionary, I would like it to open in the same pane as the Explorer guide, on the left hand side of the screen. Just another way to make Logos more cusomizable.
