True, many of us will like to have that feature, like a specific function for tile map where you can place your map then the objects then the waypoints etc etc.. but i have read before regarding this suggested-capability (try to search thru the forums im sure there is), and if you search too in this forum, on grid movements, by which there IS an example of grids which is IMO is the same as tiles.
Refering to the example, you can make your own tilemap with Construct. and btw i myself am creating a topdown view Action turn-based game. And it will be mostly dependent on tiles cuz alot of things that the player will be interacting are tiles ! hahhaha.. but really, try to search on grid movements and you can move forward from there.. just need to do a bit tweaking and adding ons, and it will be a success im sure :)
