Suggestion - Visible Levels, Pathing fixes, animal selection, expandable hearth

Split visible levels of buildings with terrain, it's semi annoying to not only need to try select the correct terrain height from +15 down to +1 each time i wish to see under the 2nd or 3rd level of a building. Alt+scroll for terrain, ctrl + scroll for buildings, this would show items on all levels above / below of built items. Shift + scroll to do both same time

Pathing fixes needed for stuck people, i've had one drop into the mines from above with no fall damage? then get stuck because they required selection of digging out, it'd be good for after 10 seconds to a character being stuck to get the same warning as if being attacked with the pause of game and possibly a marker or flashing icon on the character.

Would also be nice to have such flashing icons for when enemies attack, show us direction of where enemies are with screen icons along the edge?

Selection of all enlisted animals and people at once when highlighting over, this would be amazing
For building using shift to select multiple types of items in a line on the same level like if i wanted to remove an entire wall + doors + archways i could highlight one area then shift+click to highlight all on the same line / level at once with CTRL + click to add or remove items from such.

Modular hearth would also be amazing, refuelling all at once and stockpiling inside the hearth with (hearth*5) wood or something would be amazing thus i could easily heat an entire building with a 6 hearth / 2 hearth or such with single refuel point.
