Completely overhaul tree chopping.
Have some trees be easy and fast to cut, larger/higher yielding trees take longer and possibly even require higher tier tools.
Constitution affects chopping speed of trees.
Possibly make felling a tree a multi-step process.
Remove/change decay hits replenishing mechanic, trees grow seeds daily/weekly depending on species, bark does not grow back.
Possibly have trees gain quality/size over time, growing to 125% or gradual +/- 1-2 etc
FOR FUCKS SAKE GIVE US A LOG STORAGE BUILDING
