1) I'd like to have the possibility, if you want, to use the mouse right key as in previous releases of Calibre viewer: not to show a big window with lots of choices, but a small popup with somtehing like "copy", "search" and the like.
2) Btw I think that you should give the possibility to enable (maybe in the upper bar) a search box, like in the previous releases.

Any way, congratulations for your work and the many improvements you made! Simply fantastic, i.g., the notes as pop-up in the same window of the text.
regards!
