I uploaded a new version of the HackedUpReaderExtension:
https://github.com/bhaak/HackedUpRea...sion/downloads
Now there is
zero time penalty when opening the KindleLauncher.
Everything is postponed until you actually open up the extension's menu and then it will only collect the files of a single directory for each sub menu separately.
Also, there is a new submenu that shows the last 10 books that have been put onto the device. Although opening this menu will take some time if you have thousands of books on your Kindle Touch.
