Double-tap a word to highlight it in Kobo's built-in reader. Double-tap inside an existing highlight to remove the whole highlight, including older multiword passages.

Beta release — only tested on Kobo Libra 2, firmware 4.38.23852, with KEPUB books. Other models and firmware are untested and can attempt to run the plugin; there is no model/firmware whitelist. Back up your annotations and settings before testing.

Features

  • Native word highlighting and removal with a double tap.
  • Japanese word selection with TinySegmenter for double taps and long presses.
  • Optional NickelMenu controls for Japanese long-press words and the highlight rendering fix; both default to On.
  • Rendering correction for all highlights, including older passages and highlights with notes. Reopen your book after toggling it.
  • Highlights saved through Kobo's native annotation system, with no duplicate registry or plugin-imposed count limit.
  • Disable and uninstall flags; uninstall also removes the optional NickelMenu controls.

Install

  1. Download KoboRoot.tgz from the assets below.
  2. Connect the Kobo by USB and copy the file, without extracting it, into the hidden .kobo folder.
  3. Safely eject and let the Kobo install and restart.
  4. Open a KEPUB book and try adding/removing a disposable highlight.

To add the optional controls, install NickelMenu separately, then extract NickelMenu-settings.zip to the Kobo drive root, preserving its .adds paths. Your existing NickelMenu configuration is preserved.

Limitations and recovery

  • EPUB/PDF handling is not implemented. Japanese segmentation may select shorter pieces of a compound or phrase.
  • Removing a highlight has no plugin undo. Handling of attached notes remains unverified; do not assume a note will be preserved.
  • To disable, create an empty doubletap_disable file in the Kobo drive root and fully restart. Delete that file and restart to re-enable.
  • To uninstall, create an empty doubletap_uninstall file in the Kobo drive root and fully restart. The flag removes itself. Uninstall preserves saved highlights/notes and preferences.
  • Required native-function checks remain; finding those functions does not prove compatibility on an untested setup.

The committed-source build matches the device-tested plugin binary byte for byte. Host and ARM Qt regression checks, independent menu-setting tests, and package/known-firmware binding checks pass. Device testing covers core highlighting, both settings, disable/re-enable, uninstall cleanup and reinstall on the configuration above.
