It would be very helpful if the search results could also be viewed in the central "stacked covers" panel, in addition to the existing three modes. This would facilitate the isolated and clean viewing of series collections.
For instance, amidst numerous Batman series, I have three that share the same collection: "Batman: Legends of the Dark Knight by Neal Adams" (5 issues), "Batman: Legends of the Dark Knight by Jim Aparo" (10 issues), and "Batman: Legends of the Dark Knight by Marshall Rogers" (3 issues). When searching for "Batman: Legends of the Dark Knight," I would like to see 3 "stacks of covers" (each stack representing a series).

Right now there are two types of grid views, one that can show folders and other can show comics. The app needs the infrastructure to display a grid with both folders and comics, and then it could be possible to show search results combining both.

Depending on how your comics are organized you may be able to see those folders on the left side bar.
