As shown in the picture, you could simplify the empty sections in the task view. We don't need a "see all" button on sections with no content. Instead, you could just have a plus button on the right to add an item in that section. Maybe tapping on the section header area would open the "see all" area in an empty section - oh, it already does!
Anyways, with that change, we'd recover a lot of vertical space that way for the sections that DO have content.
