Then it is IMHO an omission as typing mistakes will remain also as there is no normal chance to correct/delete them. Not very user-friendly.
BTW, searching in sizeable (epub, not kepub) books seems to fail when trying to jump to a found text location: either the search string just won't show, or the search remains on the current page even when browsing through multiple findings.
I even managed to get a completely blank page without any escape options. Somehow I could return to the home page, but I have no clue how I did that
