The shortcuts Ctrl+<LeftArrow> and Ctrl+<RightArrow> to indent items are active when editing the task title and due date. This is undesirable since those shortcuts are default shortcuts to navigate one word to the left / right when editing text in all other applications (at least on Windows). Please use different shorcuts for indenting or deactivate them as soon as the title or due date is edited.
There are no keyboard shortcuts to focus on the next / pervious task. And there are also no shortcuts to move a tasks up or down. It would be great if such shortcuts could be added.
