I am not sure if any of these have been suggested or thought about at Faithlife, so I shall suggest them anyway.
First of all, I love the potential of Multiple Resources. I love the idea of having one main source and many others tied with it as one resource. But, there are some things I am wanting to do with Multiple Resources that does not seem too easy to do.
What I am wanting to do is tie series together. So, for example, perhaps I would like in my first panel, as my main resource, the Word Biblical Commentary. Tied to it I would like the NICOT/NICNT, Anchor Yale Bible, and the International Critical Commentary series. So all I have to do is tie one of each of the series and when I type go from Genesis 12:15 to Matthew 16:18 all of the other resources follow with. That would be great! Either it does that automatically in the background, or, when selecting series, I can search for WBC and it shows up as a dropdown list. I can either select WBC, or use the dropdown list to select the ones I want, and I would be able to do that for any series. This would also be great with dictionary series, such as the IVP Dictionary of the Old Testament: Pentateuch, Historical Books, Wisdom Books, Prophets and the New Testament side. Now for the dictionaries/encyclopedias, each book would have their own panel so if each book as an article of the same topic (not necessarily the exact same title) they each would be show in their own panel. Of course, I'd choose one of them initially to be the resource the rest of them followed. Currently, when I try to do this, I have to select each resource...individually. After you select 4 or 5 resources, the selection takes 10-20 seconds per resource for the selection to select and move up. So, if I want to select the WBC series, I have to select all 58+ resources...individually. And 20 seconds between each selection takes a looooooong time, especially when you go from series to series to series, or dictionary to dictionary to dictionary.
Also, I am seeing Logos crash when I have multiple resources for old and new testament, so that when I go from Genesis in the Zondervan Illustrated Bible Background Commentary to John in the same, with the IVP Background commentaries connected and one other New Testament Bible Background commentary, Logos crashes. It does not like more than two resources (but that was when I had selected every one of the ZIBBC AND IVPBBC AND New Testament Bible Background). When I select just one of each (ZIBBC Genesis, Exodus, Leviticus, Numbers, Deuteronomy and IVPBBCOT) and I go from Genesis 1:26 to John 1:1, the IVPBBCNT does not show up. I have to select it. But when I go back to Genesis 1:26, the IVPBBCOT does not show up. I click on Multiple Resources button and it turns out that it cleared out my selections! That is very frustrating! It makes Multiple Resources for series all but useless! I don't want to have to keep reselecting my resources when I go from one book of the bible to the next.
Now, if I select BOTH IVP Bible Background Commentaries (OT and NT) and select just one of the ZIBBC (Volume 1), it clears out both IVPBBC OT AND NT!! That is just frustrating! Therefore I HIGHLY recommend that Faithlife make Multiple Resources feature more user friendly, less buggy, less likely to crash Logos, and make it so it does NOT clear out my selections. (FYI I was making the Zondervan Illustrated Bible Backgrounds Commentary Volume 1 the resource that the IVP Bible Backgrounds Commentaries followed).
For Bible Dictionaries and Bible Encyclopedias, I think it makes sense to tie them together topically, so that even if the title is not an exact match, the article can still be shown. So if I go to the Anchor Yale Bible Dictionary or the New Interpreter's Dictionary of the Bible and I have other dictionaries tied to it, the other dictionaries can show the correct article based on topic (instead of showing nothing because it isn't an exact title match).
