Searching should interactively filter the unicode view to only show matching unicode points
Currently the actual searching of a glyph is done after pressing the Next and Previous buttons. IMO, a nicer interaction would be to filter the glyph view "live", when a character is entered, and show all glyphs that match. The next and previous buttons still retain their meanings as only one unicode point is selected at a time. (Such an interaction is similar to how emacs helm-mode works).
