I don't know whether there are significant changes coming in planned releases of Logos, but at this point the Topic Guide remains a fairly limited way to search topics across one's library (as opposed to a much smaller collection of dictionaries). As a result, a basic search of the whole library using headings, large text, titles and topics as search fields remains an important way to look for what one is looking for.
With this in mind, it is just annoying to have to continually go search for these in the list of fields and select them individually. In the same way that we used to have to type in manually #image to search for pictures but now have a quick link, it would be nice also to have something more convenient to access these fields. It could be a quick link as well or alternatively, perhaps allowing user-defined "fields" at the top of the list (like User Content in "search in") where such fields can actually be more like a collection of fields. Another way yet to do this (if it is easier) would be to have an automatic putting at the top of most frequently used fields.
