@Patrick Degenaar I had never considered this functionality before. I do see that when I draw a line with the pen tool, then switch to the eraser tool, and click-and-drag anywhere over the line, it disappears/deleted. If I needed to quickly delete a number of other objects on the board, it would be nice to use the eraser tool to do a quick click-and-drag over the item to delete it rather than click to select it and press [Delete] on the keyboard or to click the object’s menu and then the Delete option. I would suggest posting this as a Wish List item.
In the meantime, when you say “there is no “block/select” tool”, you can [Ctrl] + click multiple items (or [Shift] + click-and-drag) to select multiple objects on a board and then just press the [Delete] key.
