1. The ability to drag down multiple tiles while in placing mode. (swipe placement) way faster than tippy tapping each tile (especially road or platform)

2. The ability to remove multiple tiles while in removing mode. like number 1 but for removing.

3. A selection sub-mode to select an area to modify, (possibly while in pan mode or tile moving mode) that enables the user to drag multiple tiles or remove many tiles at once; gets triggered upon holding down and dragging.

4. A quick button to have a full view of the map.

(If any of these ideas have been proposed before, i apologize for that :P)
