Please allow us to disable the spacebar feature to shift to the end of the page. This feature makes Lumin unusable for any pdf with checkboxes, as the fastest way to check them off is to TAB to them and SPACEBAR. When you have tens or hundreds of checkboxes, this becomes a massive headache as my screen shunts itself to the end of the page suddenly, and back again when I TAB to the next thing on the list. 😵‍💫
