I've made them so long ago, but if im not mistaken they are other version for stair type thing (I'm not sure what its called exactly) for the small cliff tiles so you can have like more smooth variant of going down or up a level. And yes again fishing, picking up, sleeping, additional idle, walking etc are planned for future updates. Its just a matter of time and I'll make them. Its just time that its scarce atm but they are coming for sure :)
