+1 for the search option - right now a universal command for searching (ctrl+F) opens a custom search window. would be great if ctrl+f was moving you to search field in main window, so that it was possible to star searching not touching a mouse.
(In Opera web browser apart from the ctrl+f shortcut there's another one, more convenient for me: searching starts with "." key, so fe. to find MusicBee you just enter .musicbee. how about making "." key moving us to the search field?)
